Hello everyone!

I need help finding a fanfic I've read about five years ago? It stars a "you" character (I believe, at least it's an OC girl), Block B, Infinite and Rania.

The girl is a vampire and she's part of a group of vampires (Rania). I think she's like a princess or something and she's supposed to marry Hoya (who belongs to another group of vampires - Infinite), but she falls in love with Minhyuk (B-Bomb), a vampire hunter. Rania kidnaps Minhyuk and Zico and someone else I can't remember and feed from them (not the girl though). I also remember Hoya gets mad because the girl chooses Minhyuk over him, but when everything gets really bad and Rania fight against Block B, Infinite show up and Hoya helps both the girl and Block B.

This is what I remember about it! I would really like to find it/read it again, so if any of you knows what I'm talking about, please help me.

Thank you!
