At night, when you intend to sleepover at Miwa's home, your friends at college. You sat in the living room waiting for her, playing on your phone.

Then the front door opened, when you turned around, it was Kageyama Tobio, Miwa's little brother who was three years younger than you. He was wearing a uniform, holding a box of milk.

"Waiting for Miwa?" He asked, walked over and sat down on the couch. He knew that you would sleepover again, and he was already used to seeing you at his home.
