She’s letting him beat her... So what’s the reason why she’s chosen him, be it as a mate, or blood bag? Based on the first chapter, I’d assumed she’d be able to beat his ass into submission, but is she really this vulnerable to beatings?
Edit: I speak on the point of view that I’ve always assumed normal people are more or less helpless against supernatural forces (like a normal family being unable to fight against a ghost in their home, or demon possessing their child).
