After her family dies in a tragedy, a young woman named Jin seeks out a mysterious magician known only as K, hoping he can use his powers to bring them back. K refuses, explaining that such a wish would only lead to greater catastrophe, but he offers her an alternative: she can become his apprentice and work alongside him while she decides on a wish he can grant. As Jin begins her new role, she encounters a stream of clients who come to K with desperate requests—a father who wants to end his son’s relationship, a young woman who longs for a lost lover to remember her, and a boy who will do anything to be accepted. Every wish comes with a steep price, usually demanding the client’s most prized possession, and K’s magic operates under rules that make each transaction a moral and emotional test. Through interconnected vignettes, the story explores the consequences of trying to alter fate, the nature of sacrifice, and the weight of unresolved grief. Notable narrative arcs include the haunting tale of a flower that symbolizes a love that cannot be reclaimed, and Jin’s own gradual understanding of what she would truly be willing to give up to have her family back. Over the course of the series, Jin uncovers fragments of K’s past, the true cost of his powers, and the painful truth that some wishes, even when granted, bring more sorrow than solace. The setting blends everyday life with the supernatural, as K’s magic operates quietly within a modern world, and the revolving cast of wish-seekers paints a varied portrait of human longing. The narrative builds toward Jin’s ultimate decision—whether to make the wish she originally came for and pay the price that comes with it.
