Zhang Hao, a 4th year university student, never anticipated taking a history elective in her final year. When the professor assigns one project worth the entire grade, Hao's laid out future starts to crumple. Being sent back hundreds of years in the past was never on her 'To do' list. However, when she meets a certain maid, her entire world changes. Hanbin doesn't need to know that she can't stay...

Don't leave me... I'm still here.

Zhang Hao is a normal human who hates vampires. What human in their right mind doesn't? As a music teacher, Hao isn't interested in anything that could potentially disturb his relatively peaceful life, the life he has spent avoiding those monsters. That is until things start to take a turn for the worst... A strange boy shows up at his music studio and then before he knows it he finds himself in the royal palace in front of none other than Prince Sung Hanbin himself, heir to a family well known for being vampires. Hao wants nothing to do with him or the vampires, after all, he has far more important priorities. Unfortunately, fate seems to have other plans.
