It's spring,new session of high school is starting from today and what is our dae-in doing??

As usual sleeping.Halmeoni frustrated and started calling her name but she know that no one can wake this girl up and starts shouting and beats her up.After a hectic morning scene Dae-in hurriedly rushes to the school so she doesn't end up getting late and had to clean the school building.

Dae-in a high school student in Bomoon High School.She is a lovely kid,really??You will know about it because no one can really understand her fully or describe her charcter.

She is pretty but all clumsy.Cursing to everyone is her favourite thing and don't forget about the fights she always pull but for good reason.She is cute,kind and also very short tempered and rebellious.Her oppa Kim Seo jun is a university student and has a prosperous future ahead but this girl can't explain.

She always comes last.This year also she came last.There's saying that even if the whole school doesn't give exam still Dae-in will come last.

She reached to school and meets her childhood friends Ju-won and Hannah. Ju won is a bright student always comes first and handsome and all the girls used to always like him and had a crush on him. He is the star of Bomoon . This time also in the examination he scored the highest and became the top 1.

Hannah is a loving girl who always has a cute smile on her face. She is cute, pretty, and kind. Our Kim dae-in is completely different from them. She is bold, savage , fearless, a rebel, mischievous and also sucks in studies, but also has a kind heart because she cares for people and hides her all pain in her heart. Dae-in, Dae-in screaming came Han bo-gum in his skateboard and tool the coffee from her hand. He is also another friend of dae-in . They all are together since dae-in has moved from Seoul to Busan. Han bo gum is just like Dae-in sucks in studies but very good at sports. Basketball is his favorite game and he is also very charming. He is the honor of Bomoon because of his skills but always loves to tease her.

Dae-in was running behind bo-gum to take her coffee. Bo-gum in his skates . The whole corridor was filled with students. Suddenly a guy came walking as white as his skin as snow, his black eyes, amazing hairstyle, six feet tall was going to meet the teacher. Everyone screaming who is he?.
