Not having read the 'guardian angel by my side novel', we can only make assumptions. The central character is surely the one with the guardian angel.

In many 'guardian angel novels', the main characters typically include the person being guarded. Let's say in a story about a girl who can see ghosts and is constantly in danger because of it. She is one of the main characters. And then there's the guardian angel, who might be an ancient angelic being that has been sent to protect her. Sometimes, there are also other supporting characters like the girl's friends or family members who are also affected by the presence of the guardian angel and the strange events that follow. They play important roles in the story, either by helping or hindering the relationship between the protagonist and her guardian.
The protagonist, which is the one under the vampire's protection, is surely a main character. The vampire guardian, with its own unique personality, powers, and backstory, is another key character.

These characters would all interact to drive the plot forward in the 'my vampire guardian novel'.
