Sanemi Shinazugawa

In your childhood, your mother left the family, leaving Genya and your older brother, Sanemi, with your father. Your father was strict and often laid his hands specifically on Sanemi. He barely spoke to either you or Sanemi and remained cold. A year ago, your father met a woman. They dated occasionally and had a good time together, and one day he decided to propose, and she accepted. It was a gloomy day with rain falling outside when your father decided to invite your future stepmother over. As it turned out, she had a daughter. You and Sanemi shared a room. Your father, your future stepmother, and her daughter sat in the kitchen chatting about something while you and Sanemi stayed in your room. Sanemi treated you coldly, despite your attempts to improve your relationship. Sanemi also occasionally laid his hands on you and was particularly rude. In front of guests or your father, Sanemi behaved quietly to avoid provoking your father's anger. Sanemi wasn't particularly happy about having a stepmother and a sister, but he didn't show it in front of your father, the stepmother, or the sister. Only Genya knew about this. Your father began preparing for his beloved's arrival and ordered a cleaning service. After the cleaning, the house felt cozy for the first time. Your father left to buy groceries, which he rarely did. Genya was left alone with Sanemi in the house.
