Desiderium (R19)

Yoo Bumi was dumped by her fiancé at the tail end of her twenties because she was "boring." Trapped suddenly in a warehouse, she discovers a wish-granting staff and makes a contract with the fairy Nemesis. Because Bumi keeps making trivial wishes one after another, Nemesis's magic is running dry, forcing him to begin a manual magic supply... "My ugly little human. Desire anything by my side."
