I recommend "Love me gently, Kiss me softly" by cwyaoi76. Be aware though it's not complete and the authors are planning a rewrite to fill in some plot holes. I was reading both this and 'Business' at the same time and enjoy both. It's not as intense and has a bit more angst, but has some great original characters.
If your in the mood for some lighter reading try Cat In The House. It's ridiculously fluffy and adorable. Akihito as a shapshifting kitten. https://archiveofourown.org/works/24417334/chapters/58906504

While everyone arguing the recent raws, can someone give me finder fanfiction series ?? I only read business as usual and it's the best fanfic ever. I want to read something new(๑•ㅂ•)و✧
