They wouldn't say that if they're reading this with their eyes open. Shin's not acting like that because he found out the truth about jay. He's like that because he felt 'betrayed'. This isn't about facts, it's about what he's feeling. You can't throw some 'facts' and 'rational' words to someone who's 'hurting' because of you. You don't use your brain to someone who's using their heart at the moment. You won't understand each other that way. You have to know where shin is coming from to understand him. You don't come up with 'smart' ideas using your head.
(I'm not angry at u huhu I might come off too strong)
Please, I just don't wanna see someone saying "he shouldn't even be mad, he should be grateful that Jay's not a thug" please get out
