Good start, has potential
There is an interesting plot hidden within this read. Grammar is okay, though I myself am no expert. I think there can be some improvements there, mainly with the tense. It seemed to change at times.
Read the story now
She wanted me to icing it and noticed the little boy munching on the croissant. Shaking her head down she set the cake down on a counter behind me and I got to work.
I would try something like this.
She sat the cake down on the counter behind me, where it would wait for me to place the icing on it. She glanced over her shoulder at me, then her gaze caught the boy munching on the pastry. Looks like I’ve been caught again, I thought to myself as she shook her head disapprovingly at me.
Overall there isn’t too much to go on for plot at this time, as this is the first chapter. I do think there is a lot of potential here because the author has clearly put a lot of effort into the piece. The author is also great at descriptions and giving backstory. I am interested in reading the next chapter to see what happened to the protagonist.
Keep it up, I think as you write you will improve. You can always edit later once you get a chunk of your story written.
