My father falls in love with a witch

"Arina, Your scent!"
I murmured as I smelled her deeply. It was seducing.
"It's extremely sweet."

I fell in love with my teacher but the problem came when I got to know that she was a witch and a human eater.

I am Erin, I am going to tell a tale about my dad and I.
My dad met my mom at 19 and married her at 20. Dad loved her madly. It's normal to love your own wife, right? But it becomes a problem when his own wife is the source of the apocalypse.
