I couldn’t get used to my classmates who would only complain about boys, so I took refuge in the farthest restroom. However, there was already a visitor. It turns out that the beautiful and talented Arisugawa-san was an aloof oddball who had renovated one of the stalls into a luxurious private room!? Interested, I started to approach her, but the more I did so, the more I started to lose my place in class. On the other hand, it appeared that Arisugawa-san, who was living luxuriously like a princess in the bathroom, had some complicated circumstances of her own.
