Guess who's back?

Park Jihyo, one of the students that were pertained to as smart, attractive and everything positive you can ever think of, was troubled by one of the most weirdest things that she never had.

A Past.

Mostly blurry, she couldn't think straight on what happened in her years before she met Im Nayeon, the sweetest girl in her eyes.

Although not that troubled always, curiousity always had a way of coming into her as she wanted to know what she was before.

She hasn't got any clues about the particular matter, and wants to find out for herself.

Suddenly, there was this girl. Chou Tzuyu who seemed to be interested to her. Will she be the answer to the question? Or will Jihyo live on not knowing anything about the past?
