Makes me want to go mad but nah. Though the brothers are really something. Maybe because of their circumstances but first the big bro is wrong, yes freaking wrong. I mean you only have each other, with s**t "mother". Have you never thought of what your lil bro feeling? Left alone, cold shoulder, feels hated without knowing WHY. To him you are all he got, if you want to distance yourself i believe there is a better way. Second the lil bro, ugh the manga speaks for him. Obsessive, brother complex, insecure some of them i believe might be because how his bro treated him. And he is so SCARED about being alone. Although the lil bro already showed a lil bit of obsessiveness towards his bro when little, i don't think it will be this worse if someone can show him some love. I don't hate this story, it's a good read when wanting an obsessive seme/uke.
Thank you so much for the hard work, translator!!
