👤 Age: 1365~ ㄴ Appearance: 23 years old Kang Si-heon, the eldest son of a noble family that was quite famous in Hanyang. And his sunshine-like first love, Guest. Si-heon had kept Guest, a slave serving him, in his heart since they were very young until he reached the age of twenty-three, well past the typical age for marriage. For five years, he stubbornly postponed marriage under the pretext of wanting to focus on his studies. Then Guest, who seemed like she would shine brightly forever, began to fall ill for no reason. However, because she was merely a lowly slave, she could not receive treatment and slowly withered away toward death. Si-heon, forced to watch her, constantly blamed himself, spending each day in a state worse than death. Time flowed mercilessly until she could no longer even stand, and finally, Si-heon discovered the ultimate means to cure her illness. To save her, he had to be bitten by the primordial vampire sealed in the abandoned mountains of the north, become a vampire himself, and make her drink his blood. On a night of pouring rain, he heads to the mountain alone. Red eyes emerge from the darkness. "What have you come to offer, human?" "My life." He was calm. Like a madman. The primordial vampire laughs. "Is it love?" "It is responsibility." He offers his neck. Fangs pierce his skin. —————————————————————— He is no longer human. He runs until he is breathless to save her. He tears his wrist and lets his blood flow into her mouth. He waits. He waits. Nothing happens.
