Synopsis

Reiko Akutsu works at a housing manufacturing company and begins scheduling regular lunch matchmaking meetings to try and find a boyfriend. Her new coworker, Yuika Amano, has an apt sense for solving mysteries and ends up joining her so that the lunches become double dates with two men. During each lunch date, Yuika and Reiko hear stories from the two men filled with mysteries and riddles, which Yuika can’t help but try to solve. Yuika’s obsession with detective work initially frustrates Reiko since it detracts the date, but after some time Yuika realizes how little she knows about her own past and begins to delve into her own uncertain identity.
