Couples and breakups of Single’s Inferno Season 4: Romantic timeline

The Season 4 contestants of Single’s Inferno experience ups and downs throughout the show. From cautious moves at the very beginning, through unexpected shifts in the middle, to the final decisions — beautiful couples are formed, but dramatic moments break their hearts.

While it’s interesting to enjoy the full Single’s Inferno Season 4, following all the romantic links may be somewhat confusing. In this article, you’ll find clear explanations of all dates, the couples formed in Paradise, and the breakups that happened in Inferno. It may help you understand the show better and remind you of the best moments from Single’s Inferno.

Everything starts here, so Single’s Inferno Season 4, episode. 1 is fundamental. Viewers get to know the contestants. The participants on the show face each other for the first time — at least some of them. Two men are immediately forced to make important decisions.

The first game occurred in the men’s Inferno. They played and fought, and the top two earned the right to select their Paradise dates.

While standing in front of six girls, Yuk Jun-seo and Kim Jeong-su chose who they wanted to go to Paradise with.

The winner of the first competition of Season 4 Single’s Inferno, Jun-seo, selected Chung You-jin as his date. The couple had dinner and swam in a pool. The conversation turned out to be quite interesting: You-jin managed to lead in terms of questions, and Jun-seo wasn’t as reluctant to talk as he looked to be.

Jeong-su finished second in the men’s competition of Single’s Inferno Season 4 episode 1. He chose Si-An, and they had a great time talking. He even asked Si-an to help him with the face mask. And she invited Jeong-su to sleep in one bed.

This date was very impactful for Lee Si-an, especially the moment when Kim Jeong-su massaged her hands in the helicopter.

First impressions are very important, and the creators of Single’s Inferno Season 4 know this well. After the first day in Paradise, they placed the contestants in Inferno — Yuk Jun-seo with Kim Jeong-su went to the girls’ side, and Chung You-jin with Lee Si-an went to the men’s side. Thanks to this shuffle, no couple repetitions were possible.

On both sides, the contestants of Season 4 Single’s Inferno had a chance to talk and introduce themselves to each other. In the end, they had to announce who they wanted to go to Paradise with.

Lee Si-an had a date with another guy and it initiated heartful drama that unleashed itself later on.

The couples formed in the girls’ Inferno were revealed in episode 3.

Jang Theo is an actor, and his full name is Jang Tae-oh. He looks tough and his behavior reflects this, too. He supported this first impression with bold jokes during his date with Lee Si-an.

Still, she appreciated the time with Theo. They swam together after dinner, and this activity was full of expressive energy. During a late-night conversation, Si-an's body language showed how interested she is in Jang Theo.

Still, the romance evaporated during the helicopter ride to Inferno. Lee Si-an suddenly remembered the hand massage by Kim Jeong-su, and she became distant and cold.

From the three women and two men in Inferno, only two couples could be realized.

Jun-seo and Jeong-su went for their second Paradise night. Bae Ji-yeon was the only lady left in Inferno, as Kim A-rin won a game beforehand and was sent to the men's Inferno.

During the date with Min-seol, Jun-seo looked much more relaxed, as if he enjoyed this time quite a lot. The first day’s tension was out, and the dinner turned out to be wonderful for both parties. For Min-seol, it was more than just the joy of the first date in Paradise: she liked her partner.

After the dinner, the couple went into the pool, and it was a calm and very romantic time.

This date proved that Kim Jeong-su is great with women. He is humble and gentle. Kim Hye-jin introduced herself to him, and the two of them just had a nice time together.

However perfect it may have seemed, a crack was forming.

The events of Single’s Inferno Season 4 episode 3 did not finish here. It continued with a more competitive tone.

All the girls had to make it through a long log over a pool, while all the guys were simply standing there. Lee Si-An turned out to be the quickest and the most skillful at this challenge. As the winner, she could invite any man for dessert and iced coffee.

She chose Yuk Jun-seo, who let three girls fall into the pool and fell twice himself. Their mini-date happens in episode 4.

The start of episode 4 was pretty nice. But the later conversations of all Single’s Inferno Season 4 contestants turned out to be rather disastrous.

After winning the pool battle, Lee Si-an decided to talk to Yuk Jun-seo because she did not have the chance to before. In general, they looked like friends who enjoyed pastries together.

One moment was pretty interesting, though. Jun-seo said that he waited for his reunion with Chung You-jin, but her cold demeanor confused him.

Everyone in Single’s Inferno was gathered together around a campfire. They were all tasked to anonymously give a chocolate piece to a person they like.

The disaster was unleashed after revealing how many chocolates each contestant of Season 4 got. Drama ensued, but not because of the numbers.

The party decided to play Truth or Drink. This became the catalyst for some conflict between the contestants.

The next morning, all of the girls from Season 4 of Single’s Inferno were invited to Paradise. A surprise waited for them: three new men. A drama with these contestants occurs in episode 5.

After short conversations with all the women, the new men went through a harsh elimination game since only one of them can join Single’s Inferno Season 4. In episode 5, the girls had to decide on the lucky one via a vote.

An Jong-hoon survived that, and later on, he got to pick two women to go on dates with.

They had a nice dinner together discussing their personalities. Apparently, Jong-hoon and Si-an had too little time together to go deeper into their relationships.

After the introduction, the main topic for Hye-jin and Jong-hoon was why the guy chose this girl. They spent nice, even if short time together.

Jong-hoon's first day in Single’s Inferno was challenging but rewarding.

The time in Inferno was also eventful. Single’s Inferno got a new girl: Park Hae-lin. As a game changer, she brought fresh energy to the show. In episode 5, Hae-lin and the rest of the men had the time to introduce themselves.

Park Hae-lin chose two guys to go on dates with: Kim Jeong-su and Kook Dong-ho.

During the casual evening conversations of this episode, one of the sweetest moments of the entire show happened between Jang Theo and Lee Si-an. When the girl was in Paradise, Theo made a flower ring for her. He gave Si-an this touching gift once they were alone.

The new girl in Single’s Inferno Season 4 had two dates on one day, and they were very different.

This was the most unusual date of the entire Season 4 so far. The couple had some active adventures in the river, including water skiing. During dinner on a boat, they finally shared a conversation.

It was apparent that the initial romantic interest from both sides evaporated pretty quickly. Jeong-su proved himself as being very polite to all women — but when they discover that this is not due to preferential treatment, they become disappointed. He kept thinking about the other dates.

Park Hae-lin wasn’t too pleased with the date, either. She suddenly became bored, even if they talked like friends.

A totally different atmosphere was in the room during this Single’s Inferno date. Hae-lin enjoyed showing how different she is compared to Dong-ho. She even teased him a bit. Dong-ho did not know how to react, but he was curious about this girl.

When both were in a car, Hae-Lin had a little nap and Dong-ho made sure she had a nice rest — even though he obviously wanted to stare at her.

When everyone got back to Inferno, the show proved how cruel it can be.

First, it was a competition. Real mayhem. Girls had to battle each other for a snack with a guy of their choice. They needed to take a cap away while sitting on a male teammate. The victorious guy also had a mini-date. Lee Si-an and Kook Dong-ho won this battle. They chose Kim Jeong-su and Kim A-rin, respectively.

The girl wanted to talk to Kim Jeong-su as they did not have a proper date after their time in Paradise. This conversation proved once again how popular Si-an is. Kim Jeong-su expressed his desire to go on another date.

During this short date, Kim A-rin confirmed her interest in Dong-ho once again. She was somewhat nervous because of his date with the newcomer.

The end of Episode 6 of Season 4 Single’s Inferno was about choosing dates for the next episode. Some notable moments are below.

The couples formed in the previous episode had dates in the continuation of Single’s Inferno Season 4.

It’s the fourth date in Paradise for Lee Si-an but her first with Yuk Jun-seo. She invited him for iced coffee after her pool challenge victory in episode 3. Then, Jun-seo found a moment to have a private talk with Si-an, where he expressed his interest — beyond being just friends. It looked like Si-an did not expect that feeling from him, so she probably decided to select him for the date and get to know Jun-seo better.

While in the car, Si-an talked about her confusion at this point. She had so much fun up to Day 4, and now her situation suddenly became complicated. Four men out of six wanted a date with her!

During their dinner, Si-an felt more relaxed, and it was time for Jun-seo to talk about his worries. The guy said he could not express his feelings as openly as his direct rivals. Jun-seo was relieved and surprised to hear he was chosen by Si-an.

Eventually, both decided to take it easy, put away their confusion, and just have fun. It was a good decision! Lee Si-an and Yuk Jun-seo had a relaxed time around a small pool and a sincere talk before going to bed. Si-an was pretty honest with Jun-seo, which was difficult for her even with other girls. She openly said she likes Theo most of all her admirers, but then Si-an got overwhelmed with emotions and cried. Jun-seo still was confident they could come to Paradise again.

Jun-seo and Si-an ended up sleeping in one bed, hugging under the blanket.

The date of this couple had no unnecessary confusion. A-rin openly declared her interest in Dong-ho, and she did not give the chocolate gift to anyone else. Dong-ho has been on Paradise dates before, but it looked like he enjoyed this one the most. They could have had a date on Day 2, but A-rin chose Theo back then.

After the introduction, it turned out that Kim A-rin and Kook Dong-ho had something in common. They visit the same business center for work, and they live in the same area. Their occupations are still pretty different: an accountant and a model.

In a big pool and during their time in a bedroom, Dong-ho and A-rin got so much closer.

It was this pairing's first time in Paradise. Bae Ji-yeon was somewhat overlooked by male contestants of Single’s Inferno Season 4 — maybe they felt insecure because of her brave and non-standard look. 

Kim Te-hwan was somewhat clumsy throughout the show, and even the hosts thought he was a young guy. In episode 7, Te-hwan demonstrated his other side. He is 31, and a club owner. His slight clumsiness is not immaturity: it’s just his feature as a creative personality. 

This date was sweet and pleasant to watch. At some point, Bae Ji-yeon even hinted how jealous she was when Te-hwan sat next to the new girl in Season 4 Single’s Inferno. Objectively, the situation with Park Hae-lin was strictly in Ji-yeon’s head, and Te-hwan was never really interested in anyone else.

To seal this wonderful evening, Bae Ji-yeon and Kim Te-hwan visited an ice rink. The fun they had was unmatchable!

Meanwhile, there were some other conversations in Inferno, and one of them was certainly a breakup.

Later on, Jeong-su had a similar conversation with Park Hae-lin. The girl expressed the general opinion that Jeong-su confuses people by being attentive and caring to everyone. He repeated to her that he is bad at multitasking, so he chose Si-an.

The most notable moment of the morning in Paradise was how Si-An and Jun-Seo woke up together. The girl let her head rest on the man’s arms. What happened that night?

Si-an cared for Jun-seo’s hair and then rested on his shoulder during the helicopter ride. It did strengthen the impression that these two are an official couple now. Suddenly, Single’s Inferno Season 4 episode 8 became even more interesting.

In Inferno, the men had an intense wrestling game. The top three get to choose who to bring to Paradise.

The actual dates and the two other couple forming were postponed to episode 9. Everyone in Single's Inferno had a chance to talk more.

Some pretty important conversations happened in episode 8 of Single’s Inferno Season 4.

Kim Jeong-su surprised everyone by picking Chung You-jin for the Paradise date in Single’s Inferno Season 4 episode 9. The guy made this decision thanks to all the fun he had with the girl a bit earlier. You-jin was just cheerful with him. 

Jeong-su did not want to go with Park Hae-lin or Kim Hye-jin because they would understand there is no more place for them in the man’s heart. It seems like Kim Jeong-su just wanted to have an enjoyable and careless night — maybe You-jin is just a friend to him.

Kim Te-hwan did not follow any advice except for his heart’s call. The guy named Bae Ji-yeon as his pick for this date. Te-hwan has no interest in other girls from Single’s Inferno Season 4.

Bae Ji-yeon did not expect to go to Paradise twice in a row. Maybe she really needs space to reflect on her feelings and take this opportunity to get to know other men on the dating show.

Kim Min-seol and Jang Theo were the most disappointed people.

Park Hae-lin and Kim Hye-jin weren’t happy about staying on the Inferno island as well, but their feelings weren’t so on the surface.

These two had a wonderful time in Paradise — maybe because there weren’t romantic attempts from them.

Kim Jeong-su was pretty clear about his feelings for Lee Si-an. He explained his decision to invite Chung You-jin so that he has a harmless person who helps him clear his mind. 

Chung You-jin was totally fine to spend this night with a friend. Her experience in Season 4 of Single’s Inferno does not bring romantic struggles, so the girl enjoys her time.

This date was awkward. The couple had many sweet moments, like Jun-seo touching Si-an’s chin, or them holding hands in a car. However, both felt uncomfortable, in different ways.

Lee Si-an asked what her partner had in mind, and Yuk Jun-seo started talking about Kim Min-seol way too much. Also, the girl felt like Jun-seo was getting too comfortable around her, paying less attention than she expected.

Yuk Jun-seo relaxed and became more himself during this date. Surprisingly for him, it confused Si-an and created a tense atmosphere. Maybe both were too tired?

The emotional situation intensified in the second part of the date. Kim Jeong-su and Chung You-jin joined Yuk Jun-seo and Lee Si-an in a pub. While Jeong-su and You-jin had so much fun, Si-an was silent. Jeong-su ate instead of talking.

It didn’t feel like a date Jun-seo and Si-An really wanted to have. They lost a billiard match. And it looked like Jun-seo fell asleep right after showering instead of talking to the girl.

This date did not go well. It was apparent that Bae Ji-yeon felt rather lonely while Kim Te-hwan was too self-focused. The guy talked about his own dreams and did not care to ask questions about his partner. Te-hwan even ignored the desire of Ji-yeon to start a family by saying he is not interested in such things.

Probably, Kim Te-hwan and Bae Ji-yeon could really explore other opportunities in Single’s Inferno Season 4  Episode 9.

Meanwhile on the Inferno island, Kim Hye-jin openly stated that she has An Jong-hoon on her mind and wants to select him for a date. In response, Jong-hoon invited the girl to a private chat. After expressing his interest and shyness in communication, the man said he will select Hye-jin next time.

Kook Dong-ho found himself involved in a tense love triangle. Chung You-jin went on a date, but the other two girls wanted to talk to him. 

Park Hae-lin said she will be picking Dong-ho, and it felt uncomfortable for the guy. 

Kim A-rin was eager to know what Dong-ho talked about with other girls. The man looked more relaxed and open with A-rin.

After a somewhat turbulent evening, Yuk Jun-seo and Lee Si-an still managed to have a deep and meaningful conversation. No, Jun-seo did not sleep. They talked about their current feelings and difficulties they encounter at this stage of Single’s Inferno. Both decided to try harder in their relationships.

After returning to Inferno, the contestants had a chance to talk and share their feelings. One thing is certain — these girls and guys have found friends in this show. It’s not actually the romantic relationship they hoped for, but this achievement is absolutely great.

Girls are more open in their emotional talks. Guys often support each other silently. All six of them gathered in one room after a pool battle, and they discussed their guesses about the couples for this date, not their feelings.

Episode 10 of Single’s Inferno Season 4 features another battle for Paradise dates. This time, the female contestants had to push each other into the water.

The top three girls could select their partners. They won their starting fights and then had a match for the final placements.

Before announcing their choices, the girls had a chance to prepare. Lee Si-an took this time to talk with Jang Theo. Or, it was rather he who initiated that conversation.

Jang Theo wanted to know what Si-an feels about him. He did not want to put too much pressure on her. If Theo is only third for the girl, he steps aside.

The girl even cried, so difficult this moment was for her. Still, Si-an decided to be honest. She named Yuk Jun-seo and Kim Jeong-su as her top priorities. 

It’s over for Jang Theo and Lee Si-an as a romantic couple.

Kim Min-seol invited Yuk Jun-seo for a conversation as well. The guy made it clear he is more interested in Lee Si-an. The girl still decided to choose him if she has such a chance.

Single’s Inferno Season 4 episode 10 finished without revealing couples for the next date.

The start of Single’s Inferno Season 4 Episode 11 returned us an hour back, before the couple matching from Ep. 10. Three girls decided to have conversations with one guy, and the battle between them was like passive aggression.

Kim A-rin said she wanted to stay with Dong-ho in Inferno — well, she did it in a very unique way. However, Dong-ho got her, or he probably had the same intention. The guy delivered a similar message to both other girls: “it’s your privilege to choose, so follow your heart, but we have little time to know each other better, and I’m already leaning toward someone else.”

The girls who won the pool fight in the previous episode Season 4 Single’s Inferno made their choices: who they go on a date with.

Their date started with a serious conversation. Kim Jeong-su was strongly affected by one little act — when they were on a helicopter after a date in Episode 9, Lee Si-an leaned on the shoulder of Yuk Jun-seo. Jeong-su sat right next to her, and he took this as the end of their relationship.

However, Lee Si-an was still interested in Kim Jeong-su. Their date on the first day of Single’s Inferno Season 4 impacted her strongly. She did not know Jeong-su felt that way as he wasn’t expressing himself very clearly. Being polite with many girls did not help.

Kim Jeong-su made a sweet gift: a flower petal. During his other date, he took it while thinking about Lee Si-an.

During their dinner, Park Hae-lin explained why she picked Kook Dong-ho despite their previous conversation. She wanted to make a decision she wouldn’t regret.

Moreover, Hae-lin asked if she had zero chances with Dong-ho in the remaining two days in Single’s Inferno Season 4. The guy said their relationship is unlikely to change. He made up his mind about Kim A-rin.

These two had a somewhat weird date. Chung You-jin wanted to have good conversations, but An Jong-hoon kind of rushed to do different activities: swim after eating, spa in the room, shower before sleep. Then he just fell asleep when the girl was in the shower, and the evening was over for them.

It doesn’t feel like a couple is possible here.

On the Inferno island, Yuk Jun-seo and Kim Min-seol lost a rock-paper-scissors game, so they had to do the dishes after dinner. The girl tried to talk with the guy about feelings, but Jun-seo was thinking about Lee Si-an.

Bae Ji-yeon was sincerely bothered by Kim Te-hwan’s behavior. She talked about this in the girl’s bedroom, specifically about the guy’s phrase “I believe in being single”. Ji-yeon revealed to him that she wants a happy family.

Then, Bae Ji-yeon asked Kim Te-hwan about that directly, and his response was unclear and confusing. Something like “we need to find our differences to overcome them”.

In the final episode of Season 4, the Single’s Inferno contestants name their partners, and if they match, these couples leave the island together. Before that, everyone was able to initiate small talk.

Yuk Jun-seo was the first to invite Lee Si-an to a remote spot. It was sweet witnessing the beast expressing his feelings and Si-an enjoying the moment with a big smile.

Kook Dong-ho and Kim A-rin had a conversation under a blooming tree. Both had already confirmed their interest in each other, and they just enjoyed being so close.

Lee Si-an had another mini-date in Inferno: with Kim Jeong-su. They had some fun taking photos, but avoided deep conversations. Si-an’s heart is a mystery at this point.

Yuk Jun-seo spent some time in a room with Kim Min-seol. They were like close friends, and Min-seol said the guy 200% picks Lee Si-an. She asked him to choose an accessory for her, and Jun-seo helped her take it on — like he would do for a little sister.

Bae Ji-yeon tried once again to talk with Kim Te-hwan, and the guy proved to be totally self-centered. He even said he is not interested in anyone’s thoughts and feelings, only his. Te-hwan wondered why Ji-yeon had doubts about his sincerity.

The final day came. The women stood around, and the men had to make their final decisions — who they approached to declare their choice. Then, the girls had their final world, or rather action. They could take the hand of a guy in front of them and leave Inferno together. The women had to name their partners earlier, it’s not the last-moment pick.

Apart from a somewhat silly joke by An Jong-hoon who went away from Kim Hye-jin and then returned, there were no real surprises in this part.

What were the girls’ decisions?

The remaining girls also revealed their picks. It’s Yuk Jun-seo for Kim Min-seol, Kook Dong-ho for Park Hae-lin, and Kim Jeong-su for Chung You-jin.
