I don't think he stopped loving Myung. He will always love Myung but now he loves someone else. Loving shiwoo doesn't mean he stops loving Myung. He just loves shiwoo more??? AND I SweAR IF MYUNG ACTUALLY DOES SHOW UP I WILL FLIP DA SHIT. Shiwoo remembering won't be that good tbh because Myung and shiwoo are diffrent people and once you mix em up who do they become ??

It doesn't mean he loves Shinwoo more. It's just that he thinks Myung's dead and now the one by his side is Shinwoo. When someone you love dies, you'll love them forever and when you fall in love again, it doesn't mean you love them more. It's just that the ones alive take priority because duh, they're alive and by your side. It's not about loving more or less
GOSH I'm happy that he's decided to love Shiwoo nd all but I can't help feeling bad for Myung! The idea of somebody loving you even after death or whatever is so romantic, now it feels like Jun never really loved Myung all that much. And it's pretty obvious that Myung'll make an appearance later on, and it's not gonna be pretty when that happens.
Best case scenario, Shiwoo remembers his past life as Myung.
