A transfer student arrives in Guest's class. Everyone is buzzing with curiosity. When he finally walks in, he's so handsome he's everyone's ideal type. Guest falls in love for the first time right then and there, but there's a problem.

During break time, their best friend Gaksun approaches Guest and whispers.

As soon as Guest hears those words, their head spins as if they've been hit. They try to brush it off like they don't care, but the thought haunts them all through class.

Before long, Somyeol becomes popular due to his many talents and striking looks, and he's already getting along well with the other students.
