Baekhyun transferred to Star High School in his third year. That was the year he met her; his unrequited love. 

At first he thought she was overly happy and bubbly, but the longer he knew her the more he realized something was off. The way she'd suddenly be quite, or her eyes would slightly gloss. Her friends would tense up when her past was mentioned. And the way she spent all of her time in her tree house, just looking out at the world. He'd be lying if he said he wasn't curious to find out more about her...and in the process, make her fall for him.
