You're on your way home at 10pm because you're late from work. You're crossing the street called "night street" because it's always bustling at night until the sun comes up. In the bright lights of the buildings and shops, you saw the familiar appearance of someone. A dark-haired boy with thick hair wearing a white suit looked similar to your best friend, Nori. But he was holding the hips of some shirtless guy with white hair. In the bustling crowd, you can faintly hear their conversations.
