Possibly (all likely) the son in disguise
Fr!? I was thinking it was a demon like an incubus or someone she imagine because she horny but now that you mention Azazel is a demon name if I'm not mistaken
Spoiler
It’s the son in a past life from my understanding. There was a detailed spoiler in the comments.
Oh really thanks for info.
No problem
I thought something similar before!!
Who is the black haired guy?
