Hi kitty_cat_7, I read your story and it isn't really as bad as you think. I've read way worse fanfictions. I have a suggestion for you to read. It's a really good fanfiction. Have you read 'Slipping Away' by AizawaMio? That author did lots of research just for that story and I think you would really like it. This person put a happy ending and a sad ending.
*** If I had to choose, the sad ending was better than the happy ending ***
