I Possessed As A Childcare Extra

I transmigrated as a normal maid no. 82 in a romance-fantasy northern duke’s household.

Maid Annie’s amazing stamina and core muscles were incredible.
Life was much better than in my previous world, where I’d been unemployed.
A perfect job that matched my aptitude, and as long as I behaved well, it was a lifetime position!
With no living expenses, I dreamed of saving up my salary little by little for a peaceful old age, but—

“Enrolling in… Korea… University…?”
“How… how could Annie do that…?”

I got found out by the protagonist of this childcare-themed reincarnation novel!
The young lady started giving me intense attention, and soon we couldn’t be separated…

“Annie. Your role is important.”

Why on earth do I have to attend the duke family’s meeting?
Maybe I stayed near the protagonist too long—everything felt like side effects, and I desperately tried to run away, but—

“You’re quitting? Who gave you permission?”

The protagonist’s older brother, whom I thought disliked me, becomes obsessed instead.
Help! I’m just an extra!
