Kwon Yuri is a hard-working girl like she would do everything just to earn money. She works as a personal assistant on a company named SM Entertainment. A work she never dreamed off. The reason behind why she chose this job was to help herself to be productive and responsible on every work she do. Her parents left her to her grandmother which is in Seoul. They  travelled far away from Busan to the heart of Korea where they believed that Yuri will have a fine life. She grew up not having any negative feelings about her parents. She accepted and live with it. Her grandmother, always reminded her not to trust any boys because in the end, girls will always be the victim. She didn't had a lot of friends except Tiffany, she's also working for SM Entertainment as make-up artist. Both of them shared every little things because they treated each other like sisters since they're living under one roof. And now, her boss just called yesterday announcing that she will be the new assistant of this newly debuted boy group named EXO. It will be the first she's gonna assist a boy group since she was always assigned on a solo artist or girl groups. What will happen?
