One day you were in your art class and your sentimental teacher was talking about first love. As you listened to it, you keep glancing at a person, Sungchan.

He was your first love as a teenager but you guys are not really close. You keep glancing at him time to time. Until he caught you glancing at him, he stare at you for a few second then he chuckled quietly.

You were panicking and you looked away immediately, when you glanced at him again, he looked at you with a soft smile.
