My Devil Sister

Born into an ancient witch family, Lovett possesses striking beauty but bears a cruel destiny: each of her boyfriends must undergo a "test of true love" by her older sister, Vine. Those who succumb to temptation become sacrifices, their lifeblood drained by Vine to fuel the family's magic. In reality, Lovett was never a protected heiress, but merely a tool used to attract men and maintain the family's power. For years, she has lost love time and again, forced to work in a bar, using her beauty to lure men into death traps. Until this time, she meets Elliot. She believes she has finally found her destined true love and resolves to pledge her life to him. However, Elliot is merely an ordinary man infatuated with her appearance, lacking genuine faith in marriage and fidelity. He is quickly seduced by Vine in the backyard pool, falling into lust and betrayal. Meanwhile, Lovett unexpectedly saves the critically injured and unconscious young man Charlie. This young heir, aloof and arrogant in public, is passionate and devoted to her. While recovering and investigating his enemies, he gradually enters Lovett's world. As Vine continues to provoke Elliot and he gradually succumbs to temptation, the truth behind the so-called "test of true love" is revealed: it's nothing more than a deception by the witch family to perpetuate their power. Ultimately, Elliot becomes a sacrifice, drained of his life by Vine; the one who never wavered and was willing to give up everything for Lovett was Charlie. In the end, Charlie relinquishes his werewolf blood for love, and Lovett, as his magic fades, returns to a normal life. The two finally break free from the shackles of their families, becoming ordinary people, and spend the rest of their lives together.
