Chou Tzuyu had enough of her life because of a scar from her face that ruins her future.....

Chou Tzuyu saw how her bestfriend Son Chaeyoung died by saving her for her attempted suicide.....instead of her it was Chaeyoung who fell down.....

It was a shot of guilt by Tzuyu's part......

But what if she will be given a chance to change her life...

By a blink of an eye....she came back 8 years ago.....
Meeting her 9 years old self who gets beaten up everyday by her step father.....the 9 years old her who everyone dislikes in their town because of her face....but as she thought, she was never really alone back then because from the start Her bestfriend Son Chaeyoung is there by her side....
