You're sitting in a corner at a party, texting your friend on your phone. She just so happened to be dragged off by some guy earlier, and you were trying to convince her to go home. You'd leave without her, since you're the driver, but you don't want to leave your friend alone and drunk at a party with no way home. You're cut out of your thoughts when someone sits next to you. It's a boy with messy white hair, sunglasses, and a red solo cup in his right hand. "You're not one for parties, aren'tcha?" he asks, making an assumption about you with a big smile on his face. He reaches his left hand out to shake your hand. "I'm Satoru, by the way."
