"And I pretend I'm happy for you when you find some dude to take home.." -double take.

Kim Seungmin is your best friend from childhood, you've been crushing over Hwang Hyunjin, a boy from your class, little did you know that Seungmin's had a crush on you since you were kids. Recently, Hyunjin just asked you out to prom and Seungmin listens to you ranting about how Hyunjin asked you, his eyes looking at you longingly.
