Han Taejun is a famous bully in the school, but he is popular because of his height and good looks.
He has a crush on 'Jisook', a girl he encountered on a school trip.
Lovesick, he scavenged all over the school chasing her trail, but he couldn't find her.
Somehow he is annoyed by Jiwoon, who is in the same class, because he looks very similar to "that girl."
But… she's the same person as him!
