... Rape, incest behavior ( yeah ok the older brother is adopted but they were brought up together since birth), young brother is class A psycho.. honestly i skipped through and I don't plan to get back to it.
Sorry to disappoint but DID ( also previously known as Multiple Personality Disorder) doesn't work like that.. Personality can split only when kid's brain isn't fully "developed" so about until 7-9 years old due to continuous trauma (not saying one really traumatic event can't "do it" but..)
I can't even finish first chap.. It's just rape man, there is nothing romantic about that.. " (..) we have sex but It's one sided..Even thought I resist him he has a animal-like strength.." like seriously dude? that's not sex that's rape KICK HIM OUT and call the cops!
@Soveregin Unfortunatelly there is a lot of mangas like this one, but there are also a bunch of good plots and even totally wholesome ones, for example I hightly recomend works from Yamamoto Kotetsuko
I'm ona fence about this one because on one hand I don't like non-cons but on the other I really hope his friend will show him what a "normal" carrying looks like and stear him from this dangerous path.
