My Golden Blood (2025)

20-year-old Tong possesses a rare and powerful type of blood, irresistible to vampires. He is told by everyone around him that he has Hemophilia and must avoid anything that could risk spilling his blood. However, Tong breaks that rule and becomes a server at an event on behalf of his best friend from the same orphanage Tonkla. That’s how he meets Mark, the 200-year-old heir of the Amarittrakul family and host of the event. Mark tries to take Tong away from the other guests, but an accident happens and Tong is cut. The sweet scent of his Golden Blood stirs chaos, awakening the thirst of the vampires, including Nakan, a 250-year-old vampire and another heir of the Amarittrakul family. Mark must therefore do anything to protect him from others and also from himself.
