Park Jiwun is an average teenage girl. Well, if you exclude her academics, then,yes, she's average. She's an over-acheiving student. As a senior, many juniors, softmores, and freshmans look up to her. But, when 2PM'S Wooyoung finds out she's his sister. He looks all over the place. Using her Facebook picture to find her, he finally suceeds. When Jiwun is just casually studying in her locker, Wooyoung just goes up to her and hugs her. Jinwu looks at him like he's crazy.
