Single’s Inferno 4 has given us drama, unexpected plot twists, and plenty of romantic confusion – but nothing has fans more riled up than Yuk Jun Seo. At first, he seemed like a solid contender: cool, confident, a little mysterious. But as the episodes progressed, his behavior started raising more red flags than a toxic situationship. From avoiding tough conversations to some highly questionable physical interactions, fans are now debating – is Jun Seo just socially clueless, or is he straight-up problematic?

Avoidance Tactics or Just Plain Evasive?

Jun Seo has a habit of dodging difficult situations, making viewers question whether he’s simply conflict-averse or intentionally elusive.

At the bonfire, he told everyone he needed to go to the bathroom. Seemed reasonable – until it turned out he wasn’t going to the bathroom at all. Instead, he slipped away to grab alcohol, completely bypassing the conversation. Not exactly the most honest move.

Then there’s You-jin. The two shared a meaningful Paradise date, complete with deep conversations and even a thoughtful flowerpot drawing. But when they returned from Paradise – each with different partners – Jun Seo avoided her entirely. Rather than having an honest conversation, he chose to keep his distance. And to top it off, when You-jin was simply sitting on a swing, he was caught bad-mouthing her with other contestants. If that’s not avoidance, what is?

Physical Boundaries? Questionable at Best.

Let’s get into the real reason fans are upset – Jun Seo’s concerning physical interactions. Some of his actions have left viewers feeling uncomfortable, to say the least.

First, the unreleased clip from his Paradise date with Min-seol, which Netflix recently released. Instead of handing her his drawing, he threw it at her. It came off as dismissive and disrespectful, raising eyebrows among fans.

Then, there’s the infamous bed scene with Si-an. While some viewers brushed off the moment, many found it disturbing. When Si-an tried to sit up, Jun Seo pushed her back down onto the pillow – and not in a playful way. The action felt forceful, making many question whether he understood the concept of personal space. If anyone still considers this kind of behavior masculine, it’s time for a reality check.

And there’s more. During a helicopter ride, he pushed Si-an’s head onto his shoulder so she could rest. While this might have been intended as a caring gesture, the execution was rough, making the moment feel more forceful than affectionate. Even Si-an herself seemed taken aback. In the Episode 9-10 trailer, she explicitly told Jun Seo that she wanted him to be more gentle with her. If someone has to remind you to treat them kindly, that’s a problem.

Casual Speech or Just Plain Rude?

We get it – informal speech happens. But Jun Seo? He took it way too far.

Throughout the show, he kept referring to the girls as “Ya” (which, for non-Korean speakers, is a casual, borderline rude way of addressing someone). Min-seol, trying to be diplomatic, pointed it out gently – saying she didn’t mind but hinted that others might. Translation: She was definitely not okay with it.

Si-an, on the other hand, had no patience for it and directly told him to use her actual name. Even host Lee Da-hee had to step in and call him out, saying, “No woman is going to put up with that.” If it takes this many people to correct your behavior, maybe it’s time for some self-reflection.

Mixed Signals or a Backup Plan?

At the end of Episode 8, Jun Seo pulled Min-seol aside for a private conversation. He asked if she’d want to go to Paradise with him, making it seem like he had made up his mind.

Then – plot twist – he picked Si-an instead.

Fans were left completely bewildered. Was he just caught up in the moment? Did he want to keep Min-seol as a backup plan? No one knows for sure, but one thing is clear: his decision-making skills are as confusing as his behavior.

Final Verdict: Red Flag or Just Clueless?

Jun Seo started off as a fan favorite, but now his reputation is taking a serious hit. From dodging responsibility and acting forcefully to speaking disrespectfully and making baffling choices, he’s either deeply awkward or a walking red flag.

What do you think? Is Jun Seo just socially unaware, or is his behavior a genuine issue?
