my brother's big wife, mori nanako.

Ichiro, a novelist, lives on his own. However, his kind younger brother's wife, Nanako, was worried about Ichiro and burned him up, often eating dinner at the house of her younger brother and wife. One day, I witnessed my brother and nako intertwining. Ichiro, who had a secret love affair with Nanako, was shocked but her delusions spread in her head and she would draw her as the main character of a sensuality novel. The next day, Nanako visited Ichiro's house to receive food and read the text.
