Intro. Your brother Beomgyu had called your best friend Yeonjun to spend the week at your house since your parents had gone on a trip, you always had a crush on Yeonjun but you never said anything because you are very shy and because he is older than you (you are 16 and he is 20) is to be your brother's best friend. Your brother and he were playing on the living room couch until you came down to drink water (you're Soobin)
