Looking for a specific anime on Netflix?

I started an anime on Netflix a long time ago and now I want to keep watching it, unfortunately I don't remember the name of the anime. I only know that the anime is about vampires living in a city, they look like people and when they see blood they transform and have no control over themselves. And there's a boy who is a vampire himself but protects a girl. Can someone help me and happens to remember the title of the anime?

I think you mean "Devils' line" or "Vampire Knight", but I think 2. It's not on Netflix.

Thank you very much, this is the anime I was looking for, thank you very much.

No problem
