Iijima Ryosuke, who continues to take women, is advised by Gen that his instincts will become dull if he only embraces women for work. It is true that the women who come to him are like carp on a chopping block, with no way out.

Since he was aware of his sexual proclivities, he ransacked the women, thinking that he could approach them himself in private. He happens to be on good terms with Hiiragi Shizune, a married woman who catches his eye, but...

At the same time, Ryosuke meets with Tsuyuguchi Keiji, one of the founders, who asks him if he would like to sleep with a certain married woman.

Ryosuke succeeds in having sexual relations with the wife, Fujishiro Kasumi, and even begins to have her as a client.

While having relations with both Kasumi and Shizune, Ryosuke begins to think more deeply about his future.
