私の蛇妖旦那はちょっと変です

The Yannick bloodline demands its daughters forge demonic pacts. Sisters Yelena and Melania follow this tradition, but jealousy leads Melania to deadly schemes. Reborn before their fateful choices, Melania tries to claim Elias, unaware of his nature. Yelena bonds with the dormant demon Miles, who awakens to protect her. As the Myra Selection nears, Melania's plotting inadvertently strengthens Yelena and Miles's bond, showing true magic lies in love, not pacts.
