From Tokyopop:
K is a wizard who can grant wishes--all he asks in return is that which is most precious to the wisher...
Mourning from a horrific loss, Jin Ryu wants K to bring back her parents and brother from the dead. But when K tells her that a wish such as this can only lead to greater tragedy, he agrees to take her on as an apprentice. Now Jin observes K with his various and sundry clients: A father who wants to put a stop to his son's relationship... A young woman who longs for her lover to remember... A boy who will do anything to be accepted...
