The story revolves around Lin Wan, the heroine of Cinderella. She was burdened with the burden of her family and struggled to make ends meet by working part-time, but due to an accident, she met Gu Yang, a cheerful fitness instructor. Gu Yang was attracted by her tenacity and took the initiative to approach and help her. Their relationship quickly heated up. However, Lin Wan's colleague and "good friend" Suman, who is friendly on the surface, is actually jealous. She covets Gu Yang's excellence and gentleness, and cannot bear the happiness of Lin Wan who is "not as good as herself". Suman carefully designed a trap, taking advantage of the information gap and Lin Wan's inner inferiority, to gradually alienate the relationship between the two, and revealed the "truth" about Lin Wan's embarrassment, which caused strong opposition from Gu Yang's family. Under numerous misunderstandings, realistic pressure and constant provocation, Gu Yang and Lin Wan repeatedly pulled closer and pushed away. The deeper the love, the more real the hurt. In the end, when Lin Wan became disheartened and chose to leave, Gu Yang was shocked to realize all the truth, but now he was faced with the dilemma of being tied to the interests of the Suman family. The climax and reversal of the story is that Gu Yang, who seems to be sunny and flawless, has hidden secrets and pressure behind his family. Suman's actions also stem from her own tragic obsession and the shadow of her original family. This is a deep sadomasochism about trust, self-esteem, redemption and mutual growth. In the end, the two must work together to break the external shackles and inner demons in order to usher in the belated but determined moonlight.
