Znakey's manga / #Psychological(129)

‘I’ is actually an assassin, born (? in a lab, emotionless. In a mission he killed a man who was raping a child and was about to get rid of the witness when he remembered a cat he’d found as kid and his boss/father shot it. He instead erases the kid’s memories. Years later, that same kid, Kyosuke, is a prostitute and ‘I’ one of his clients (he gives him the name ‘Itou-san’ when trying to guess his name). Despite the dark story, their relationship is interesting and sweet, if a bit yandere-y.
