I Will Change The Genre

I reincarnated into my favorite novel genre.
I became the villainous aunt who mistreats the young protagonist. But I felt sorry for my nephew who would grow up as a protagonist in a revenge plot, so I’ll try to take care of my nephew until his uncle shows up and takes him as per the original plot.
But then…
“Oh, mom!”
I’ve become his mother all of a sudden?
“I don’t know your circumstances, but how could I bear to separate a mother from her son? Lady, come with us to Winterwald.”
Hey, Kim Luca! How are you going to fix this misunderstanding?
