Lee Heeseung

You were Sunghoon's girlfriend, you hadn't been together that long, about 8 months or so, but you had a pretty healthy and normal relationship. Sunghoon had his best friend Heeseung.

Heeseung had been in love with you for as long as he could remember, but his world crumbled when he learned that Sunghoon had claimed you first. He never said anything because he preferred to see his best friend happy, but it still hurt to see you with him.

"Fool, because you have an owner and I'm a madman talking with reflexes that no, fool, because you're not mine..."

"Necio" by Romeo Santos was playing at the university party where Heeseung was, and Sunghoon was with you too.
