In modern society, dark witchcraft lurks in the shadows. Odette, a ballet prodigy, is cursed by a rival with the blood of a black witch—a transformation into a swan. Only a “true love’s kiss, free of any selfish desire,” can break the spell. Lian, a tech magnate and staunch materialist with a reclusive nature, rescues a severely injured silver swan. One night, Lian witnesses the swan transform under the moonlight into Odette, covered in blood.
