A serious civil servant named Hiiragi Shiro lives for the streams of his favorite VTuber, Yobuchi Ruki. When the broadcasts become less frequent, Shiro grows anxious. One day he encounters his neighbor, Kurusu, who is visibly exhausted from work-related insomnia. Shiro offers to help him sleep, and the two begin a routine of spending nights together. Shiro soon discovers that Kurusu is the person behind his beloved VTuber persona. The manga follows their developing relationship as they navigate the secret intimacy of these “after night” hours, which must never be mentioned on stream. Shiro, a dedicated but cautious fan who values boundaries, must adjust to being physically close to the very person he idolizes from afar. Kurusu, though charismatic on camera, reveals a vulnerable side and becomes increasingly dependent on Shiro’s presence. Their bond deepens through stolen moments of comforting sleep, playful teasing, and the shared weight of hidden identities. The story balances comedy with heartfelt romance, exploring themes of obsession, trust, and the fragile line between fan and creator.
