MC used to like Han Seo In during highschool but accidentally witnessed Han Seo Ins step brother kiss him (i think)
i think dead bro is core of their broken relationship, blond hair before is bro of seme and seme had black hair in high school, so i think there is incest or something.
I'm kind lost about the relationship between the MC and the brothers(twins?)... Someone help? .____.
