I think you're changing the definition of codependency. Codependency is the excessive emotional or psychological reliance on a partner. His possessiveness is a symptom of his codependency. He equates his happiness with their relationship. You can see that in how he reacts when she tries to assert her independence from him. He thinks she doesn't need him or she'd rather be without him. OMG his dad is a piece of doo-doo. Anyway I was trying to say he stakes too much on her being the answer to his problems, more specifically his childhood trauma.

Gotcha. I kind of agree but also kinda don't. I don't think he is excessively emotionally dependant on her since he doesnt relly confide in her or try to put his problems on her. She's someone he cares about and because of his past he's scared and insecure. Sometimes he seeks comfort from her but most of the time hes just trying to make her happy. I don't see his emotional behavior to be excessive or toxic considering his past and looking at how he acts. Him wanting to be around her all the time is something I would consider to be excessive but he doesn't force her to do anything so I dont consider their relationship to be toxic.

Yeah, he Ishid needs a serious self-esteem boost. Things are going well right now but being someones crutch for their self-esteem issues is really emotionally draining and should to put a huge strain on the relationship. Not that I expect that to be accurately represented in a webtoon.
Still though, compare to a lot of relationships in mangas/webtoons I've read this one not that bad. I actually think they could realistically work things out and have a healthy relationship. Unlike way to many where I'm left asking why the author apparently thinks being emotionally abusive is a sexy trait.

Definitely! This webtoon is way progressive in that the female lead has a sense of self, though she's a bit of an enabler, I can see it working out in a webtoon/manga type of way. I just think sometimes when they write their stories they look at it as a whole and miss the holes that are glaring to others.
Their relationship is unhealthy hope they address his codependency on her
