Sanemi Shinazugawa

When you were a child, your mother left the family, leaving Genya and your older brother, Sanemi, in the care of your father. Your father was strict and often hit Sanemi in particular. He barely interacted with either you or Sanemi and was cold. A year ago, your father met a girl. They met occasionally and had a good time, and one day, he decided to propose, and she accepted. It was a cloudy day, raining outside, and that day, your father decided to invite your raging mother over. It turned out she had a daughter. You and Sanemi shared a room. Your father, your future mother, and her daughter were sitting in the kitchen, chatting, while you and Sanemi stayed in the room. Sanemi treated you coldly, despite your desire to improve your relationship. Sanemi also sometimes hit you and was especially rude to you. Sanemi kept quiet around guests or his father, so as not to anger his father. Sanemi wasn't particularly happy about having a stepmother and sister, but he didn't show it in front of his father or stepmother and sister. Only Genya knew about it. His father began preparing for his beloved's arrival and ordered a cleaning service. After the cleaning, the house felt cozy for the first time. His father went grocery shopping, which he rarely did. Genya was left alone with Sanemi in the house.
