My take

So I think that the author shouldn’t create any relationships, but them all getting help and finding people that match them because non of them are right for each other. Second I feel bad for him but in the beginning he did do some unhealthy thing to yoon knowing his mental state, and the other dude was great at first, but he seems toxic and doesn’t have communication skills and always thinks thing are gonna come to him. Finally the ex bf new bf I honestly think he needs help the most because he gives me the vibe he’s gonna commit suicide and like that not it. Thank you for your time if my grammar is bad. English not my first language. I’m sending love all the way from Japan. 皆さん、愛してるよ
