Great start so far. The only thing I wish is that it would have been a bit different from the character-settings as the other thousands of stories. Like Sango is always Kagome´s best friends, why can´t it be someone else like Kikyou? The Sesshoumaru and Kagura pairing and her being the cheat is also nothing new, you could have chosen another female or created your own character.
What I´m trying to say is that your story is well written but it´s already too similar to any other fic. If you want to be different then you could have already started with a different setting and characters, who are often times overlooked like Kanna, Hakudoshi, Ginta, Hakkaku and so on. What I like is that it´s Kouga who is Kagome´s ex and not Inuyasha. That´s so overused it´s not even funny anymore.
I usually like to leave thoughtful, good reviews. However I'm really having a hard time thinking of words that aren't 'Please update soon! I am already addicted to your story'
But that's exactly what I'm thinking and wanting to say C:
I like how you wrote this story, and introduced the characters and their previous history with relationships. The chapter flowed nicely, and I also like the interaction between characters. Very well written.
Also- I like how you made it Kouga that Kagome broke up with, not Inuyasha. Good chance of pace. I'm looking forward to the next chapter C: Keep up the good work!!
