I'm sorry that i don't understand, but why are y'all mad that the main character has trauma???
stop it with "Yohan deserves better" as if relationships are easy. Or as if he has to be protected from the world. Yohan is a grown ass adult and consented to this casual relationship. Its not Jihyun's fault that he has mental burden. Its not solely upon him to forge a relationship with Yohan. Yohan likes him and the least he can do is be accommodative of the MC's mental health.
PTSD doesn't just go away
firstly, i hate that blond mf. he acts as thought hes entitled to the ML.
secondly, Sangwook is touching him like that, undressing him, despite him having said no.
i feel so uncomfortable
I'm tired of the the older male lead. He really doesn't know how to end anything cleanly
