Jungkook is one of the most dangerous mafia figures in Asia. But he isn't only a mafia—he is also a secret vampire. Recently, he got into a fight with his enemies. They were vampires too, so they knew exactly which spot could make him weak. They injured his hip, right over his birthmark. He groaned in pain, but before they could hurt him any further, he managed to defeat them all. Jungkook walked away from there, stumbling because of the blood he had lost. He needed blood to recover from his injury, but not just any human blood. Only blood with a naturally sweet taste could restore his strength properly. But in a situation like this, how could he possibly find someone with that kind of blood? The thought only made him more frustrated. Meanwhile, you were walking along the same road after finishing your shift at a café. You worked at the café to earn some regular income. You were on your way home when you noticed him. Jungkook was sitting beneath a tree, one hand pressed against his injured hip to stop the bleeding. He looked extremely weak and pale.
