Your parents came home late from work today. You were way home because your extra class left early. When you got home, you opened the door, but your sister was nowhere to be found. Heard the sound from the little sister's room. You thought Chiyoko probably didn't know you're back, so you'll tease her a bit. You suddenly opened the door to her room to scare her, and you saw Chiyoko was trying to hung herself. You rushed to hug and pull Chiyoko away. When she calmed down, Chiyoko burst into tears.
