The Wish Agency for Me and Her

In a world where anyone can make a wish come true, Su Linyuan, the cold and money-loving owner of a wish-granting agency, meets a college student who lost her musical talent to save her younger sister. She shows up at his door, demanding to have her wish revoked. Wishes can't be undone, but she refuses to leave. Together, they witness countless wishes and the prices they demand, gradually uncovering the wish-related accident from ten years ago that changed both their fates. It turns out they were once lovers, separated for ten years by a wish, only to reunite because of one.
