I Reincarnated as a Parenting Story Extra

I possessed a mere maid in a Northern Duke’s household just a background character in a romance-fantasy novel.
A lifetime job with stability, as long as I keep my head down and stay out of trouble? Sounds perfect!
I planned to save up quietly and one day escape for a peaceful life...
But then
You went to… a Korean cyber university?
How- how could Annie know that…?
The heroine reincarnated from modern Korea found out I’m a transmigrator too!
Now I’m stuck to her like glue, constantly in her spotlight… and worse, her overprotective brother starts to take notice.
“You want to quit your job? Who said you could?”
The male lead of this childcare story the one I thought would ignore me—has become obsessed!
Help! I’m just an extra!
Annie’s chaotic survival tale as an ordinary extra in a not-so-ordinary childcare drama begins!
