IF SOMEONE SAYS THAT SANGCHOO IS A PIECE OF SH** IT MEANS UR ARE IMPATIENT AND INCAPABLE OF UNDERSTANDING HUMAN NATURE, it's easy for you to say that he should confess but put yourselves in his shoes who's having a hard time describing his own feelings. On the other hand Jaeyoung is not saying anything because he doesn't know what Sangwoo wants, he's waiting for him to say anything because he doesn't want to get ahead on their relationship like he mentioned on the chapter where he compared their relationship to an elevator and a staircase. Guys it's not that easy for some people to express themselves, I relate myself to Sangwoo because It's hard for me too explain anything but that's because I got misunderstood often and meanwhile in Sangwoo's case he's confused about his feelings because he never felt that way before. So I hope you understand them, don't be one sided and always looking for who's the wrong or right between people even in real life UNDERSTAND both perspectives
What I think here is that jj wants leo to self reflect what he did but since leo didn't know what he did he just made an option instead T-T that's just sad jj surely have high pride between them but anw it's not like leo would not consider his problem I think he's not that selfish considering that he did switch for jj
