41 parts Complete MatureIn the labyrinthine underbelly of Busan, a city where night never seems to end, reigns Choi San, a centuries-old vampire with control over the darker elements. His world is one of cold dominance and strict hierarchies-a place where humans are strictly forbidden and vampires thrive under his iron rule. San's immortal existence is marked by calculated power moves and blood debts, with no room for the vulnerabilities of love.
On a rare blood moon night, an unexpected incident disrupts the delicate balance: Jung Wooyoung, a rebellious young photographer obsessed with capturing what should not be seen, inadvertently crosses into San's domain. Seeking the thrill of forbidden shadows, Wooyoung's lens captures more than just the eerie beauty of the night-he captures the fleeting image of San himself, shrouded in mystery and allure.
Intrigued and infuriated by the breach, San confronts Wooyoung, intent on erasing the event from the young man's memory. However, the encounter doesn't go as planned when he can't erase his memory.
