Why do I Smell Blood? (my hero acadamia: bakagou kasuki x reader)(AU)

a world in which good and bad guys are still just mere fairy tales till one day...... (y/n) is a young girl with a not so good back story, but the vampire that says he can help doesn't have a good tale to tell either.
(y/n) feels like she's going crazy, she has accepted her fate but doesn't know how to fully accept who she is.
will he be able to help. or will his denseness keep him from noticing the troubled girl in front of him.
(this is only my second story, and im still working on the first. but i feel like this will go smoother since ive been think about this one more.)
