‘Don’t be like that. I feel bad for the maid TT’
I pitied the maid side character forgotten by the author, so I left a comment.
The next day, I became that pitiful maid, Maria Mayer. Because of her zero presence, I was called a ghost.

So I thought all I needed to do was work hard, but then people started becoming interested in me.
The future crown prince and the grand duke! “I can’t feel your presence at all. Who exactly are you?”
The crown prince, Elias, was interested and yet cautious of Maria and decided to place her beside him.

There’s nothing I can do if you can’t remember me. I just need to make sure you don’t forget about me from now on.”
I’m sure this is our first meeting, but the grand duke approached me as though he knew me.
I-I… I’m just Regular Maid!
