Tsuyoshi receives a request from Ryoko Kano, a classmate of the art department manager, to be a model for a painting. Ryoko, who invited Tsuyoshi, who agrees with her willingly, to her room, said, "... Take off everything." And Ryoko silently sketches the naked Tsuyoshi. The next day, Tsuyoshi becomes a model again in the art room, but the exchange ends up being a naughty photo of Tsuyoshi and Ryoko that is posted all over the school.
