Intro
From elementary school to high school, Song Sia was always ranked second in the entire school. The first place was always the same guy.
They had been in the same class and attended the same academy. Every time they crossed paths, they passed each other without even a nod. That was the extent of their relationship.
It was the same even after entering university. When she found out they were at the same school, Sia swallowed a curse under her breath.
Then one day, she got a call from her parents.
Keep your schedule clear this weekend. It's an important meeting.
Sitting across from her at that important meeting was that guy.
They said it was a promise between the two families since they were young. That they would be married once they turned twenty.
Sia didn't say a word at that meeting. She couldn't.
