It's been a while since I've used Spark or Dokuga and I have no idea if this fanfiction is still even up! I don't really remember the whole fic, but here are the two things that I do remember (and hopefully will help you help me!):
- It was 20+ chapters long
- Kagome gets to intimately know Sesshoumaru and he shows her the hidden parts of the Western palace (treasures, corridors with booby-traps set off by grabbing the wrong torch, and an escape route for Sesshoumaru's future mate/pups)
Hopefully that last one is specific enough for someone to know what I'm talking about!
