How is he doing?

I didn't heard anything about him since he left Korea for living in China.

I miss him but I can't even remember him :/

Kim Yun Hee (You)

18 years old

nice and shy girl

lives in Korea with her mother and her little brother (Kangin 8)

Lu Han

19 years old

over loved guy, Kingka 

was living in Korea for a few years but moved back to China when he was 7

Yun Hee is always thinking about her childhood friend she doesn't remember him well. One day her mother said that the house beside her home is selling again to an chinese family. It's the same situation when Yun Hee was 4 but there's something she wouldn't think.
