@happy okay so basically yeongwon (black hair ) got bullied by seoin's brother ( seoin -> blonde hair) his brother was shown in the previous chapters , basically his brother was sick and suffered from cancer but he was so evil that he bullied yeongwon cuz he hated seoin so the last incident was basically seoins brother and his friends hitting yeongwon so hard that he had to quit taekwondo , plus it was published publicly but without names , seoin knew that yeongwon had suffered from this but he never knew who did it to him , fast forward to this chapter , seoin figured it out and got so frustrated and mad about it and he's acting like it was yeongwon's fault for not telling him so he pushed yeongwon away from his life so he could take revenge or something but the thing is that yeongwon was clearly the victim , so instead of just talking it off he literally just ruined everything between them and made yeongwon feel even bad for not telling him which does not make sense to me cuz obviously yeongwon didn't tell him to just not remember his trauma again!
