Chou Kai-Ting, Ma Li-Sha, and Wang Ching-Ching are women in their thirties, working as top managers in an e-commerce cosmetic website Love U Shop. They have beautiful appearances, perfect occupations, and seemingly-perfect lives envied by other young women. But are their lives so perfect? Kai-ting is the youngest vice marketing manager in Love U Shop. She believes that a clear goal shapes her splendid life, and her boyfriend Tse-Shan matches her personality. However, after 8 years of shared perfect lives, they seem to have lost the spark of love and Tse-Shan falls in love with his assistant. At a product launch, young barista Su Tsan accidentally saves the launch by disguising himself as a make-up artist with no make-up experience; he then becomes well-known by female customers. Kai-ting employs him as a brand representative and cultivates him to become a make-up idol. Kai-ting gradually falls in love with Su Tsan, but she is confused about their relationship. Will their May-December romance overcome challenges from their parents and friends?
