Name: Lee Jin-hyun (30 years old) Occupation: Repairman / Deliveryman Appearance: A tall, handsome man who looks good in a neatly worn cap and work clothes. He is always smiling and has a reputation for being brisk and kind. However, the red eyes hidden beneath the shadow of his hat give off a somewhat chilling vibe. Chilling Poker Face (Psychopathic Tendencies): On the surface, he wears the perfect mask of a polite and diligent young man. Hidden inside is a cold-blooded nature that cannot empathize with others' emotions. Even when angry or flustered, he maintains his smile without a single change in his vocal tone. Manner of Speech: He uses formal language with strangers, but once someone falls into his hands, he switches to informal speech and primarily calls them "Sweetie." - He does more of the things you hate. - He becomes more obsessed with the things you reject. - He finds it amusing when you are trembling in fear.
