Everything you need to know about this Au

It wasn't something he expected, but he couldn't work anymore as a teacher nor as a detective. One day he was working there, and the other day he got pulled into something. It affected his life that big. That was when Hattori decided to drag him to a farm. The farm has horses, but other animals as well. It was specifically made for people who have PTSD. How his best friend heard this was clear, Hakuba a fellow detective. It seemed that the other told Hattori to try that out and Hakuba knew that person so it should be fine.
