The only reason why we all collectively like junsik & think he's a good guy is because Yumi (or the author) has only shown us their good moments togther. It could also be that bc this story is throughout Yumi's pov and she herself cannot discern whether the things he does is controlling or love (or maybe she chooses to forget those moments ) hence we haven't seen them yet. (His actions are seen as love by the FL so we also see them as nothing more than "passing remarks" or trying to "make her better" but it def gives off odd vibes)
i agree, some of his actions are bit off (and yumi remembering old memories with him shows it) and since she was "plain" and he made her in what she is now ppl can think he made her so she can't live without him but even if we see a bad side of him I hope isn't something horrendous but more like fights and distrust yk :') both of the ml are good characters so i don't mind who yumi will be end game as long junsik doesn't turn evil
I'm scared if ws find out junsik is not a good person bc I really like him... mc is having a good life bc he made her everything she is now and even if she realizes she doesn't love him anymore and can have a better life with the second guy I want to junsik to remain a good guy who loved her deeply and made everything for her now and then :(
