Han Jisung was a very popular person. He was intimidating and cold to people (Although the girls didn't care and litterally fangirled over him), except you. He was cold and rude to you. Nobody cared though, because he's hot and popular. Of course.

[AT SCHOOL] You see (AND HEAR) a large group of screaming girls while your walking to your locker. Han Jisung was in the middle of that fangirl group, obviously.
