Sulli has always been a little taller than a lot of people, so she is always usually seen looking down, usually when she walks or talks to people.       One day as she walks to her class, she bumps into a new student, Oh Sehun. She's surprised to see someone who's taller than her, and awestruck to see someone so handsome.       She thinks she met the one. 

Choi Sulli and Oh Sehun are neighbours. They used to be a cute best friend when they were children. However, they aren't in good terms lately. Because, Sulli got a new boyfriend and she ditched her own best friend. Unfortunately for Sulli's boyfriend, he got caught two-timing by Sehun. Sehun wants to tell the truth but will he be able to?
