Synopsis: Blood Bank

In ancient times, the world was shrouded in darkness, but fortunately, humans were spared by their natural predators – the vampires. As a token of gratitude, humans voluntarily offer their blood to them, leading to the establishment of "blood banks". During one such visit to the bank by Shell Overlord, the son of an esteemed bank master and his heir, he notices a peculiar banker named "One", who appears to be one of the rare humans immune to the pheromones, a specific scent that renders humans incapable of resisting a vampire's command. Notably, One is not the only one who stands out. Shell is an "abnormal" vampire, who delights in being governed by humans despite being superior to them. Intrigued by One's defiance to his pheromones and that he is the only mortal capable of dominating him, Shell implores One to indulge his submissive desires. As they are forced to conceal their passionate tryst, it becomes evident that their emotions for each other surpass the societal norms and may never be accepted.
