Seoul High, a school that isn't much different from any other school in South Korea. Students get judged amongst each other for all sorts of characteristics. 

Suzy Bae, a 200lbs student who is the top ranked student in the whole school. Constantly gets made fun of because of her appearance. She does not believe in makeovers and does not plan on getting one any time soon. Suzy has a loving boyfriend that she trusts with all her heart. She strongly believes that this relationship will last for a very long time. 

Jong In Kim, a transfer student who is basically what any girl would go for. Tall, tan, smart, good looking. His chicness makes all the girls drool. However, he has his eyes on someone else as soon as he arrives at his new school.

Minho Choi, a classic ladies' man. He slyly uses his fellow classmates for whatever he wants without them even realizing that they are being used.
