Best friends brother (I know I've done this before but he suits this category so well)

Sunghoon, your best friends older brother, was adored by everyone and he was really popular with the girls

Sunghoon was the pure definition of handsome and sweet, he'd always treat you like his own sister

he'd protect you when needed and you grew to like him, unfortunately though, he had a girlfriend

"Want to have lunch with me?" he asks
