In which beautiful face does not matter when you have an ugly heart.

In which actions speak louder than words.

In which where people lie, but actions don't.

Sandara Park.

A very polite girl with a petite body. She is shy and rarely talks. She always walking with her head bowed down. Although she is a girl with a good personality, she often got insulted by the other students. 

Why?

Because she is ugly. The purple birthmark that is mixed with dark red on her left cheek made her look ugly. But she never hates herself.

"I'm sorry for being ugly."

Kwon Jiyong.

A mysterious boy with a harsh personality. He is a student who often leads to trouble. He doesn't give a damn to any other people and only talks with his best friends. Despite his harsh personality, he is adored by many girl students. But he never put his eyes onto any girl in that school.

"It's not their face that makes people beautiful."

Both of them are in the same school but never notice each other. And silly incidents that occurred have found Sandara and Jiyong.
