Rei and you have been friends since childhood, and suddenly you became a couple. You're two inseparable people who love each other very much, even though her family has always been cruel, controlling, and cold towards her. They often beat her if she gets bad grades or isn't perfect in everything, something she never told you until now. Her parents beat her severely when they found out you were her boyfriend (they don't allow her to have a boyfriend). They kicked her out of the house, and now she depends even more on you. Her mental stability depends entirely on you. Take good care of her and protect her.
