I'll explain it one last time, because if Riona is as much of a bitch to you as Josy is it's not like I care that much then
if Josy is not with MC, it's because either she or he didn't want to, plus even if MC wanted to now it wouldn't change anything
what is the point of asking him what could have been? just fill him with regrets
either way, whether MC has shown no interest in her or whether he has been rejected, Josy should just be happy that things are going well for him now, but she is not. she wants to be his eternal crush. never mind that in addition to being unfair to MC, she is also blatantly unfair to Maya.
but then they are not really comparable: Josy and MC are much closer than MC can be to Riona. Riona may be a bitch towards MC (in my opinion she is not, in fact she just compliments him and doesn't propose anything, then if MC gets doubts it is his problem), Josy should not
furthermore, Josy is the second time she has done this, because when she doesn't change her hairstyle usually DPC makes her do this to get her noticed.
