For me, the plot is cute, sweet, and light. I like how the writer developed her characters in the story. Also, it might be because I'm a sucker for strong female leads so much, and I feel like Anna is really brave for standing up for herself against all odds, especially against her selfish mom.

I guess the downside for me is the technicals (grammar, punctuation, word usage, spelling). However, for a non-english speaker, I guess the way she wrote this was okay. It's described very straightforwardly. It's clear and it's concise. That, in my opinion, could be a double-edged sword because, yes, it is straight to the point; however, that is all we get from the scene. It lacks other relevant descriptions that would make the scene a lot more vivid. That is just my two cents. This story can improve, I hope.
Kudos to the writer for writing this light-hearted story (Well, it seems light-hearted for now anyway). Keep writing! :D
