There were some complicated meanings at the end of the movie, which needed to be interpreted from many angles. According to the plot, when the vampire hunter Professor D and the werewolf girl Millie were looking for vampires, they encountered a small town that was attacked by a mysterious person. Millie told Professor D that she had heard that there was a formula in this town that could cure vampires, but this person did not appear. Professor D decided to go to the town to find the formula and save Millie and the others. In the town, Professor D and You-Know-Who had a fierce battle and finally found the formula. But when they returned to the city, the vampire had already returned. Millie and the others tried to stop them, but Professor D had already drunk vampire blood and become a vampire. At the end, Professor D and the vampire entered a bar together. Millie and the others were also there. In this bar, Professor D turned into a vampire, Millie and the others tried to fight him, but Professor D became stronger. In the end, Millie realized that she needed to find a way to make Professor D lose his vampire identity, or they would all be hurt. She successfully used a special herb to turn Professor D into a human, and finally they successfully solved the crisis.

This ending also hinted that the conflict and confrontation between vampires and humans might continue because they were both facing their own identities and responsibilities. At the same time, this ending also showed Millie's courage and wisdom. She had successfully found a solution to the problem.
