Sutang is a vampire who transmigrated into an ABO world and differentiated into an Omega. Initially lacking fangs, he later developed Alpha-like fangs. He survived by secretly drinking blood from Xi Chenyi, an Alpha General. At 19 years old, he is underage in the interstellar age where adulthood is 20. He is 178 cm tall, penniless, and attends university. Despite his Omega physiology, he retains a vampire's night vision and a bold, somewhat mischievous nature. His relationship with Xi Chenyi evolves from blood-dependent to romantic, as he navigates arranged marriage threats and social media scandals.
