Asian Drama

A sexual scandal between a math teacher and a student in a prestigious high school ended in tragedy. 4 years later they meet again, now as adults, to reveal the corruption in school and to regain one's reputation as a teacher.

Ji Yoon Soo is a high school math teacher with a bright smile and a positive impression of others. She is a hard-nosed and stubborn person who has to push ahead with the decisions she has made. She is a math geek who loves solving difficult problems and teaches students to purely love math.

Baek Seung Yoo is emotionless and has no light in his eyes. He used to be a math genius who appeared on a quiz program at the age of five and surprised the world by solving college-level math problems. He was admitted to MIT at the age of 10 but dropped out at the age of 12, and suddenly disappeared.

Im Joo Kyung is a high schooler who is upbeat and positive about most things – except for her appearance! She hates the idea of being seen in public without makeup, but fortunately has become a self-taught makeup expert, with a little help from a plethora of internet video tutorials. What she has learned online has transformed her life. At school, she is known as one of the prettiest girls in class – although she secretly lives in fear of her schoolmates discovering what she looks like behind the makeup! In fact, there is only one person from school who has ever seen her minus her “mask” – Lee Su Ho. He is a top-grade student with impressive basketball skills. He is also dashingly handsome, and many of his female classmates have a crush on him. However, Lee Su Ho harbors a few dark secrets from his past, and shuns attention in class. Slowly, these two individuals become drawn together – and learn more about one another’s secrets!
