WOAHHHHHHH!! SQUELING WITH HAPPINESS!! Modern setting. There are devils everywhere and they feed on human emotions (envy, greed etc). Ml took a train home and met Fl. Ml's power won't affect the Fl, hence he took the fl as his assistant (smt) in a cosmetic surgery clinic along with the other devils. Ps, looks like harem because deym boys be hawt. Ending was abrupt but mehhh
Call me the Devil
