Akari, a beautiful wife living in an apartment complex, was living a happy life. I have no complaints about my husband, but I felt the charm of "male" in the body of Mr. and Mrs. Yoshino who lived in the opposite room, and I was interested. One day, the president of the housing complex proposes to hold a get-together, and Akari offers her home. Leaving her husband and Mr. and Mrs. Yoshino at home, she was attacked on the landing of the stairs by the union president who suddenly changed on the way to her room.
