Taeyeon is a high school girl who is very good in her academics. She is the salutatorian of her batch being beaten by Choi Siwon, their superstar valedictorian. Taeyeon is actually the school’s nerd but she doesn’t care. If there is someone that could save Taeyeon from being a nerd, that is Lee Donghae.

Donghae is a rich guy who is the school’s heartthrob. He is very good in sports but bad in academics. He hates studying so he always skip classes and practice dancing or sometimes soccer. Taeyeon and He were very good best friends. He always accompanies her to everything and helps her with everything she needs. Sometimes, Donghae even helps Taeyeon to be with her ultimate crush, Siwon.

Choi Siwon is the school’s superstar. He is not just a heartthrob; he also got the brains and the perfect body. He excels in both academics and in extracurricular activities. He has that six-pack abs that could make any girl melt. Siwon is very kind and considerate to others. But sometimes, he is very playful. He always got into trouble but always manage to escape. He is friends with Donghae.
