At age six, Shuhua becomes Soojin’s best friend, Soojin was on the school playground watching the children running and playing, she was a very shy child and didn't have any friends at school

-Why are you sitting here alone?

Soojin looked surprised to hear another child's voice, she turned to face the small girl standing next to her, the girl is wearing the school uniform but her shirt is all dirty, she has short hair with bangs and one of her front teeth is missing

-I don´t have friends

-Everyone has friends

The girl had a funny way of talking and Soojin just smiled at her while shrugging

-Don't worry, my name is Yeh Shuhua and I'll be your friend

And that's how they became best friends, Shuhua was the opposite of Soojin, noisy, clumsy and quarrelsome while Soojin was shy and quiet, they couldn't be more different and more perfect for each other, as the years went by the bond between them became stronger and stronger and it seemed like nothing would separate them ...

-It's Soojin for you....please leave and don't come back

 Shuhua left Soojin's house and they never spoke again, two months later Shuhua left for Japan, she had gotten a scholarship to study at Tokyo Institute of Technology.

10 years had passed since the last time Soojin saw Shuhua and there wasn't a day she didn't think about her, she had never hated Shuhua, on the contrary, Shuhua's feelings were reciprocated, Soojin loved her too and that's why she rejected Shuhua that day.
