I really did like your story. It would have been better if it was a little more realistic n they went a bit slower, then mayb the emotional parts would have meant more. I still liked it :) on 2 the prequel!
I'm gonna give you my honest opinion. I think (imo) this goes forward too fast. I'm not sure how long they've been together, a week? a month? I don't know cause I've lost the thread. I mean, you don't get engaged in real life either (okay,I know this is fiction, but anyway) after two weeks. You could describe things more, so getting in to the story would be easier. Otherwise I like this story, and I can't wait to read more.
