The Queen and Her Two Sons

The vampire queen had her heart stolen and lost her life to a human adopted son she once picked up and raised. A thousand years later, revived by an arch-enemy, she sneaks into the side of the adopted son while hiding her identity to regain her heart and seek revenge. The gloomy adopted son continues to madly test the "substitute," and the arch-enemy who upholds justice is just searching for the lost "benefactor." When time winds back with the battle to recapture the heart, the thousand-year revenge drama reveals who was really binding whom.
