Jaehyun is your step brother... Your dad and his mom married and so you two become siblings but not blood related. He hates you but, inside he love you and care for you,he has a feeling for you more than a sister... He loves you soo much but never show it...he always act cold around you...

"where were you? I've been looking for you everywhere,your friend's house, bookstore,cafe and everywhere,...where did you go without telling me huh? Do you wanna see me go insane with worries sick? Where the hell did you go? Answer me..."

He shook your shoulder hardly and looking at you with his red eyes, there's even some tears in his eyes. He's probably worried for you while you just went to the market to bought some decorational stuff for Christmas after school. He didn't found you in the school nor anywhere.

"I'll die if I lose you Y/N,you know that right?"
