A slow burn for your hashira mentor. ... He saved your life that night. He never expected you to become the person he would risk his own for. After finding you barely standing against a demon, Rengoku takes you on as his Tsuguko. What begins as training slowly becomes something neither of you can name. Long missions, quiet nights at his estate, tending to each other's wounds, and the way his eyes linger a little too long. Rengoku has always known how to control his flames. Yet somehow, the burning desire that is growing for you is the one thing he can't seem to contain.
