Fr they be acting like this "subtly guilt tripping people to get what you want" is fine.
Gyeol was clear with his feelings from the start, even put up boundaries, then sohee was buldozing her way in as if she hasn't been warned enough. Afterwards, she gets upset because the person whom she's been overstepping is mad at her??? (He'll then be nice, she'll push her feelings more and unless she comes to her senses, the cycle will repeat and will probably consume them both.)
Relationships built with an unstable foundation will naturally have many issues, unless both are devoted to becoming a better person, irl, it will eat you up catastrophically.

I'm on gyeols side. Leave him alone. And if she even cries after he shouted no and everyone gets on his case i'm gonna be super annoyed. Its making me feel like I don't wanna read further but I want to stay for gyeol.
