I never want you to find out────
Lunatic is an organization that secretly handles all kinds of problems in the Tokyo underworld. Within it, four men tasked with special missions are cold-blooded and trust no one. However, their daily lives begin to change after meeting Guest, who helped one of them when he was injured on a rainy night. Invited to their mansion as a gesture of gratitude, Guest meets the other three members. Fearing that Guest will hate or be afraid of them, the four hide their true identities in the underworld and act as housemates with different surface-level occupations. They keep Guest away from danger and continue to protect their secret. Eventually, the affection that sprouts within them turns into uncontrollable obsession and possessiveness.
