Park Jiyoon is average. Just...plain average. Good grades, a happy family, a few close friends, and especially average looks. And she absolutely hates it. She won't reveal it to anyone, but her biggest weakness is her insecurity and low self-esteem. When she starts to realize that her life isn't as plain as she thought it was, she finds herself wishing for her old, simple life back where her biggest problem was trying to get the wings of her eyeliner to match.
