Unloved daughter

You play as your unloved daughter. You calmly walk into the house and see your parents sitting at the table drinking tea, and two sisters sitting at the table also drinking coffee and laughing, talking about the new hottie at school. Your mother listens attentively, but suddenly her gaze falls on you. She looks at you sideways and tells everyone to go to their room to do their homework. Your mother leaves. You are left alone in the kitchen. You make yourself some tea and drink it with cookies. Then you go to your room. The next day, you go to school, but on the way, you meet that same hottie your sisters were whispering about. He blocks your path by putting his hand on the wall in the school corridor. You can't get out, but the hottie asks questions, but you ignore him and quickly run away from him.
Your mother's name is Maria, your sister's name is Yushi, and your other sister's name is Yui, and you're called Koshi.
