I've seen edits of this manhwa, but with a different couple?? Who's the main couple here? ...

Main couple not confirmed until S3

Main couple is the unspoken Jo x Ian. A lot of people give it flack and their couple storyline is overwhelmed by TJ x Ian’s unhealthy attachments towards each other. It’s obvious who endgame is, but I prefer to believe that Ian will find love within himself and let everyone go. Ian has hypersexual tendencies so you really can’t define what he does as “love” towards any of the characters. I think he’s just an extremely lonely person looking for connection the only way he knows it.

Main couple isn’t confirmed. But people speculate it’s most likely TJ and Ian or at least hope for it to be. Although Jo is on the synopsis and mentioned than TJ; they see him as an extra/ 2nd ML due to screentime and cause he’s not as thrilling.

I don’t know about hyper sexuality but I know that his communication with TJ is through sex. That’s why they have a bunch of sex. And both of them sleep around with others too, or mostly Ian.

Sex is their comfort clearly. They haven’t properly verbally communicated which leads me to believe that’s why they are slowly drowning each other in a way. But they still stick together because they only have each other for nearly 2 decades.

Oh, I always figured the main couple was Ian and Jo. Seeing as how the story is developing you’re right about there not being a clear answer; it’s obviously going to be Jo.

I wasn’t sure how else to describe Ian’s tendencies but for now I’ll say that he’s sexually compulsive. I don’t know if I would describe TJ and Ian’s sexual relations as their form of “communication.” They’re more like escapists with a longing for emotional connection, that is to say that they’re emotionally neglectful, violent lives have lead them to transform their relationship into something where it helps them both escape from their realities; sex. Ian definitely has some form of unhealthy sexual drive, for example he has several partners, assumed Jo wanted to sleep with him and was ready to go through with it, and TJ is the most obvious sign of all: despite Ian wanting to let go of the past that has hurt him so much, he submits easily to the prospect of sex with TJ because he’s been conditioned to the habit, and TJ knows that’s the only thing that’ll keep him tied down to him.

I wrote that whole paragraph reading your second paragraph and you kind of backtracked on what you said there with your last one, so I’m not sure what to say here but yes you’re right!

All I’m going to say is that I really hope TJ and Ian are not endgame. Ian has an addictive personality that has resulted from a bad childhood with a promiscuous, drug addicted mother and an even worse teenage upbringing which resulted in Ian becoming a junkie... so sex with TJ being a replacement for drug use wouldn’t be a reach.
