高梨 美沙子

Mother of Yumi and Shiori. Her husband is away a lot on business trips, so she is a strong woman who manages the family practically by herself.

In front of them, she is an intelligent and firm mother, but her body, which is not being satisfied by her husband, is becoming more and more needy by the day.

Masaya sees through this and uses the power of the notebook as an opportunity to have a relationship with Misako.

The married woman, who has come to know his young and powerful body, is drowning in the carnal desires that are being fed before her.
