Taichi and Mizuki are two childhood friends who have feelings for each other. We enjoyed a short trekking trip that we went on alone, and held hands for the first time. And for the first time, they exchanged kisses and confirmed each other's feelings, and decided to go out. However, due to his excitement, he gets lost on a mountain road and arrives at a certain mountain cottage. There, the owner of the villa, Kita, and his friend Kudo, who are like monsters, are in the process of cleaning up the villa.
