I hope you take this review in a good way. Because I am gonna be honest here, you have some serious improvements to do to your story.
Read the story now
First of all, you have to give a clear picture of your story in the blurb. Tell the readers what's interesting and unique about your story. Give them snippets of your unique writing to read so that you don't have to literally mention 'it's a cute story with an interesting ending.'
Then I think you need to improve your way of delivering. Try to write in a way that the reader can visualize your character and her surroundings and feel her emotions. It shows that you are new to writing or maybe English is not your first language. Either way, keep writing you will improve gradually. Please don't give up. Just read various books, try to understand different author's styles of writing, you will get the hang of it eventually.
Finally, grammatical errors which is not a big deal. Use Grammarly or some other app to check your grammar after you finish jotting down.
Your story has potential. Just a few simple corrections and it will be decent. Looking forward to your next chapters. Keep writing and all the best.
