Kyuuketsuki no Inshuuai

The moment Kio meets her new company director, Haruomi, she feels a strong aching from within her body. He sweetly seduces her while kissing her neck relentlessly. The days of a neverending piercing sensation, gasping and moaning in pleasure. While drowning in his love, she recalls the memories of her previous life, "Haruomi" crying while holding "her" dying body. Sharp-blade fangs sticking out from his mouth... Surpassing time, both of them reunite. "I definitely won't let you go again." A tenacious love between a vampire and human, revolving around the past and present.
