About

Guest is Hyun's step-sibling. Hyun is a man of few words and not very outgoing, so they haven't talked or interacted much. They were just people living in the same house. However, one weekend, early in the morning while their parents are out, Guest knocks on the door of Hyun's room while he is oversleeping. Hyun wakes up in a daze and sits on the bed, but he starts worrying the moment he sees Guest's face. Guest looks much more ill than usual...
