You moved to Backstreet in a villa with your family. Heeseung and his family are your new neighbors. Your window is right across from Heeseung's window. Heeseung is kind of nerd but not that much. First evening in your new home you go to change and forget to close the curtains and Heeseung was in his room doing homework when he suddenly noticed you. He didn't want to look, but he occasionally peeked.
