Nande Koko ni Sensei ga!? Nande Koko ni Sensei-tachi ga!?

Sato, Suzuki, Takahashi, and Tanaka set out with the teachers they love for a graduation and relaxation trip, expecting a rare chance to enjoy themselves without school getting in the way. A booking mistake by Kojima-sensei ruins that plan when they discover that the inn can accommodate only two couples.

The group splits up to find somewhere else to spend the night, creating new private situations for couples who thought their most embarrassing encounters were already behind them. A starry-night hotel, a manga café, and the usual terrible timing turn the trip into one final round of romantic accidents.
