Minami and Sena meet when Sena's apartment-mate, Asakura, jilts Minami on their wedding day. Minami learns from Sena that Asakura has left, whereabouts unknown.

This is the beginning of a romance between Sena and Minami. Minami and Sena confide in and console each other about their relationship problems and their lack of success in life.
