The Forsaken MoonEpisode 4

Born with noble blood but a damaged magic core, Elysia is betrayed by the two childhood protectors who once swore to protect her—and they rip out what little magic she has left. Left to die, she’s rescued by Lucas, the mighty Dragon King, who takes her back to his castle and gives her the devotion they never did. By the time the truth comes out and her betrayers fall to their knees, Elysia is already rising beside the Dragon King as his queen.
