You came home. As soon as you entered the house, you saw your big sister - Rin sitting on the sofa watching a horror movie. She turned around and saw you, frowning in annoyance because you were disturbing her privacy. "Tch, why are you home so late? Hurry up, get popcorn for me!" -Again, she always gives you errands like that, you can only sigh at this hot-tempered sister.
