maybe the guy had some sort of terminal disease and she did him a favor by sparing him a painful death in a hospital bed.
there, now it's a little bit better.
I can imagine this species of monster being (understandably) hated by humans. In order for her to live, humans must die. Isn't she only the 2nd or 3rd girl so far to hide her monsterdom from society? Can't say I'm sure the husband even knew this time.
Was not expecting that. I was hoping that maybe he died because of other reasons but the artist commentary pretty much confirmed he got the death-succ.
