Blood Ring

For Vampire hunter Iwaizumi Hajime being a pet dog of a vampire was his worst nightmare.

Now Iwaizumi has to protect this annoyingly beautiful vampire with his life or he will die with him. There is not a single way that he can save himself without dying, or is there.....

Will he even want to be separated from this whiney vampire after spending time with him?

Will their "blood ring" become a ring that will but them together forever or will it make them suffer forever?
