Curvy K-cup married teacher Kyo Minami pairs with clumsy rookie Narukami to preview a school trip. She spends the journey fixing his errors, then localized record rain strikes on the first evening. He also failed to reserve their hotel, forcing them into the inn intended for students. Frustrated by a day where nothing works, Minami buys alcohol and makes him join. Thoroughly drunk, she mistakes her junior for the husband absent from her bed and begins clinging to him.
