The top is a sh1tty as5h0le who traumatized the bottom to the point of trying to commit su1c1de while sleeping.
When the top was jealous of the pink hair dude, he got the bottom blindfolded, tied, nak3d and stuck a d1ldo in his ass and showed it to the pink haired dude(w/o the bottom's consent).
There are so many mangas(even toxic ones) out there without the top traumatizing the bottom.
P.S. I wrote this so that other people know what this manga is about and don't waste their time reading it if they don't like that.
