Psychopath: MCs Watch Out!

A Psychopath transmigrates into a familiar world right out of a novel and meets the Main character. The Main Character becomes good friends with our Resident Psychopath who spends most of his time taking care of the MCs Parents, Friends, and Lovers while the MC was busy getting stronger. The Pain, Despair, and Anguish were like steroids to the Playful little Psycho as he played butler to the MCs Household. [Congratulations! You have meet the Requirements of the System.]
