Taichi and Ameri, childhood friends, enjoyed a short trekking trip and held hands for the first time. They then kissed for the first time, confirmed their feelings for each other, and agreed to go out after the trip. However, they got too excited and got lost on what should have been an easy mountain path... At a loss, the two arrived at a mountain lodge. There they found the owner Kudo and his friend Kita, who were cleaning up the lodge in preparation for closing due to a lack of customers.
