OMG! I become My Dragon Husband’s Father’s Only Cure

I’m Rosie Conti. My parents sacrificed me to the Dragon Clan, forcing me to marry Crown Prince Colin. But I hate this marriage. After discovering my husband’s affair, I decide to find his adoptive father, Dragon King Derek, and ask him to end our marriage. But then I discover Derek is poisoned and doesn’t have much time left. And somehow, my heart blood is the only cure! To stay alive, I’m forced into an unexpected bond with my own father-in-law. But why does my heart race every time he gets close? Is it fear… or am I falling for him?
