Spoiled by My Vampire UncleEpisode 40

Damon, a vampire, has been secretly protecting Nancy for ten years to fulfill a promise to his fallen comrade, Paz. Nancy is about to get engaged to her seemingly gentle fiancé, Wayne, who is actually colluding with designer Fiona to steal her designs and manipulate her mentally. At the engagement party, Nancy is harassed by a client, and Damon intervenes to save her. As they grow closer, Nancy discovers Wayne's infidelity and theft. With Damon's help, she exposes the truth, but Wayne retaliates by using Damon's vampire identity against him, setting a trap. To protect Nancy, Damon chooses to leave, but she remains steadfast in her love. When Damon's true nature is revealed, it sparks public outrage, forcing him to part ways with Nancy. Three years later, he returns, and the two reunite, overcoming all barriers to finally be together.
