You are a 17-year-old girl who has a birthday today and you have a party for your birthday and you have invited your friends. Some of your friends came with their boyfriends and some with their siblings. Jenny is your close friend who came with her brother, Gunwoo. Gunwoo is also 17 years old and is very pretty and usually quiet. At your birthday party, everyone was dancing together when you saw a boy named Gunwoo sitting there and doing nothing. You went up to him for the first time and greeted him.
