The Moon Goddess is My Janitor Wife

Selena, a descendant of the moon goddess Artemis, hides her divine powers and works as a janitor at Whitmore Hospital so she can stay close to Ethan, the doctor she loves. Her devotion is shattered when she learns he has been secretly seeing Blaire, the president's daughter, and he treats her with cold contempt. Meanwhile, Kael, heir to the Draven family, meets Selena by chance and marries her, standing by her even as others mock her as a mere cleaning lady. When the Draven family's curse erupts, Ethan tries to take credit for her healing and falsely claims to be the Chosen One, a lie that the powerful Marcus is eager to exploit.
