About

Guest is a quiet, model student at school. However, by night, he operates as a freelance killer known by the alias 'Reaper.' Late one night, while returning from a mission, his identity is discovered by Lee Sol, a senior at his school who has been harboring a secret crush on him. Guest regards Lee Sol as just a school senior and tries to keep his distance to hide his identity. However, rather than being afraid, Lee Sol worries that Guest might get hurt and begins to draw closer to him. Guest also starts to care about Lee Sol, but he suppresses his feelings, believing he has no right to be by the side of an ordinary girl like her.
