Hot For Slayer

Ethel is an old vampire. She gets injured and is protected by a vampire slayer Lazlo. He just recently lost his memory. He keeps asking Ethel questions which she dodges. He knows she does not tell the truth about his profession and their relationship (he is supposed to kill her).

Ethel takes Lazlo home. They go out on the town and are attacked by an ancient vampire. They both get injured. At this point, Lazlo regains his memory. They default the ancient vampire. Ethel considers attacking Lazlo. However, he confesses his love for her.

Apparently, Lazlo has been in love with Ethel for a very long time. He now lives across the street from her, and has been spying on her for the duration of her living there. She drinks his blood, which he gives freely. We find that he has retired from the slayer profession. He killed all the hit men they sent after him. Ethel and Lazlo become a couple now. They travel the world. And sometimes they return back to Ethel's home.
