I highly enjoyed this fanfiction. It's very well written, your portrayal of Hazuki is spot-on, and where you've expanded on what little we knew about her backstory seems like a perfect fit to me.

I could picture the Karaoke bar scene, and it really was adorable. I'd love to see more of the Youko/Genma/Hazuki trio (Particularly Hazuki, though) in future, There really isn't enough good fics around them.

It was interesting. Not bad.

Hazuki is hawt.
