I agree with the above comment about Frank being quite quick to accept it all, but I do think this is a very cute little story :) I'm not big on Frerard, but it doesn't bother me so much either. Still, this is one of the few Frerards I've read. Now THAT'S special.
So, yes, I liked this, it was very adorbs.
One more thing, you may want to space the text a bit, just to make it easier to read. I know, I know, "that's how it is in books!", but it's a bit different when it's on a computer screen.
