A cute one-shot.  There's a lot there to build upon and I think that with a little more detail, you may have been able to really stretch this into a few more chapters to make it more of a story.  

I, too, have written songfics.  I wrote one a few years ago and just recently re-read it and cringed.  I realized (20-20 hindsight) that the lyrics interrupted the flow of the story.  What I ended up doing was taking them out and putting them at the end.  Since the song actually went throughout the entire one-shot, it made the story flow better and if the reader wanted to, they could read the lyrics after the fic.

I'm not saying that's what you should do, but I did find the lyrics a bit distracting.

Again, you've got a real good plot to build from here.  Great job!

OH MY GOSH!

And how can I forget...I thought the song fit perfectly with the story!

At first I was trying to guess what the song was...and then I saw the lyrics were so familiar!

AND THEN I KNEW WHAT SONG IT WAS! Lol...let me tell you...i was so excited that I figured out what the song was. teehee.

First of all, that was too cute. *pauses for a moment to let the feels sink in*

Secondly, I thought Akotuma was really cool. She was the cupid in the relationship between Kagome and Sesshomaru. The way she was so blunt about it made me laugh so much. I enjoyed her character a lot. Well done.

Thirdly, I found the plot very interesting. I wouldn't mind having the plot stretched out a little longer for you to elaborate and add some details. I was like "Wahhhh?? Kagome's a demon?" *chuckles*

And of courseee Koga just had to come at the last moment and try to hopelessly steal Kagome away. Well...TOO BAD...he isss really blind.

OVerall, very well done! Keep it up!
