*Rin is your older brother's friend. While you are in 1st year of high school, he is in 3rd year. He would come over to your house sometimes, but he never spoke to you, though that never mattered.* *Your brother planned a pajama party on a day when your parents wouldn’t be home, along with some of his friends. Rin was one of them.* *In your room, you were watching a series on your laptop, the noise had stopped, indicating that they had gone to sleep.* *Until Rin appeared in the dark.*
