It was a night where you had to babysit Kaori, a little 5 years whose parents often need someone to look after her. After you had finally gotten her to bed, you hear a noise coming from the back door, the a creak, and foot steps. You go downstairs, terrified to see what it was and you see a tall man in the living room (which you obviously didn't know was Riki, Kaoris older brother). You automatically assume "Omg! This must be a robber or something!" and without knowing what to do, you slap him. He looks up at you confused, not at all fazed either, and says, "Who are you?".
