Bae Yuri is an slightly clumsy, sarcastic, happy-go-lucky 16 year old girl, finally returning to Seoul after living in London for 10 years. She's looking forward to having fun in high school, and living a normal life - with no intentions of falling in love.

That is until she falls for a boy.

Literally.

On her first day back in Korea, she manages to trip and fall face first onto the good looking stranger and locks lips with the guy. They immediately form a hatred for each other.

And it turns out he's her next door neighbor. 

Great.

Throw in a couple of jealous girls, backstabbing friend, parties, bubble tea, pocky sticks, cute boys, and love and it seems Yuri's going to have a fun year.
