"Before you ask me out, fix your appearance first."

Shion, a 17-year-old high school girl who had her first love confession cut short by the merciless words of her first lover, has grown up to be a beauty salon employee with a sophisticated appearance and solid skills and is now living a fulfilling life, using her humiliating heartbreak as a springboard 12 years later.
However, despite her beautiful transformation, she has no luck finding love. Concerned, her best friend from high school arranges a blind date. Shion's innocent presence immediately attracts the attention of the men, but all she can do is smile awkwardly. Then she hears a man making fun of a woman's appearance, and suddenly, she loses her self-control, and her mind is taken over by the trauma of a long time ago!
12 years have passed, and nothing has changed... Shion is shocked to see a photo from her high school days of her first love and herself, a 17-year-old with a dull appearance. She unintentionally tears up the picture, and at that moment, she travels back in time to 2010! She is reunited with her first love.
During confusion over whether it is a dream or reality, Shion, unable to accept her reflection in the mirror, undergoes a complete makeover using the makeup techniques she has cultivated over the past 12 years.
She looks 17 years old but is 29 years old on the inside. Shion has undergone a complete makeover and begins her second high school life.
