my brother's wife, shichikai nana.

Shunsuke stayed at his older brother and wife's house and went to a preparatory school. It's a day when my beautiful and kind older brother and wife, Nana, gets worried and delusional. On the other hand, vegetables are frustrated with their estranged married life with their husbands. One day Shunsuke witnesses the scene of nana's adultery. Shunsuke, who saw the face of a rude female of vegetables instead of his usual gentle face, begged for them. In the room next to her husband sleeping, she is in a manner of rape with her brother-in-law shaking her waist.
