Nanbu develops a tendency called "Lucky Pervert", which always lands him in borderline "happy" perverted incidents. After losing his job due to this 'power', Nanbu goes to work at a deli owned by an old friend who is aware of his condition. One day, a customer, Agano, comes in and, as usual, Nanbu causes a series of incidents, including unintentionally spraying Agano with water, falling down, and burying his face in Agano's crotch! However, instead of getting angry, Agano is kind and caring to Nanbu and he can't help but fall in love with him!
