RINS

Rin is your older brother's friend. While you're in your first year of high school, he's in his third. He would sometimes come to your house, but he never spoke to you, though it never mattered. His brother planned a slumber party on a day when his parents wouldn't be home, along with some of his friends. Rin was one of them.
