For a thousand years, Nyx, the Goddess of Night, has loved Helios, the God of the Sun. But during the divine marriage selection, Helios deliberately chooses the cow Belle for 99 consecutive years, all to postpone their wedding and indulge his beloved pet. Heartbroken by his betrayal, Nyx finally gives up and marries Erebus, the God of Darkness, who has loved and protected her since childhood. Realizing what he has lost, Helios desperately tries to win Nyx back, only to face endless trouble caused by Belle, who has transformed into a woman. When Belle steals Helios's divine necklace and drives him into a destructive frenzy, the gods face a deadly crisis. Both Erebus and Helios are willing to sacrifice their lives to save Nyx. But only one can truly give her the future she deserves. As the truth unfolds, Nyx chooses the love that never abandoned her and embraces a happy new beginning with Erebus and their unborn child.
