The protagonist's older sister. A perfect superwoman who has perfect scores in every subject. After her aunt took over as their late parents' school's principal, Mao was sent overseas to study for 3 years in order to not interfere with the school's succession and Mei's plans, but she managed to complete her studies in a year and a half. She missed her brother so much Mao masturbated every day while fantasizing and/or having phone and video sex with him.

She came back in order to take the school back and make true the dream of her parents of a school that teaches about true love.

Before the story starts, Mao and the protagonist were already in a sexual relationship. She's returning home and is anxious to spend every day having sex with him. She idolizes her brother and sometimes goes over the line, and when she does, it's time to punish her.

Mao is actually Mei's daughter. When Mei had sex with protagonist's father, who she made really drunk in order to steal from her older sister, she got pregnant. She was going to abort, but the protagonist's mother begged her to not do it, as she didn't want the child of her loved one to be killed. After Mao was born, the protagonist's mother took her to raise as her own and left her family's house, together with the protagonist's father. Mao knows this but doesn't accept Mei as her mother and always say that her true parents are the protagonist's parents./
