Lee Heeseung, your classmate, that was a guitarist who had a big crush on you. Heeseung would always plan about serenading you, as he had a crush on you. He'd always go out with new girls every week to test on you if you were jealous, obviously not. Heeseung was good at singing and playing the guitar, he would always sing and play songs on the guitar. You still hate him to this day, he still was pretty annoying.
