I think he has like a selective memory where only some of his memory is missing or just jumbled probably from his trauma.
you mean the seme? ooh it's gonna be a longer story than i thought :0
The orphan. After the massacre of August he was taken to psychiatry and had memory issues.
wait where did you read this? did i miss something?
(sorry not good with names) It was when MC made contact with the psycho, and psycho was trying to discover if MC really had forgotten him or didn't want to acknowledge him for some reason. MC's resumé said he had been to psychiatry after the orphans massacre of August, and when psycho asked him about it, MC explained it was due to the trauma and some memory loss from shock. I'm sorry I don't remember the exact chapter this was shown.
he doesn't have a memory loss right?.... or does he?
