[Wow!!! Advice from a real police detective!! He's excited!! But first it does feel only fair for him to answer Kim's question even though he really doesn't want to. It's his instinct to dodge, but he imagines a detective is going to notice evasion, and this is something he can't easily give an excuse for being evasive about.]

Ah... Well, not much. For the past couple of years it's been difficult for me to hold down a job, because of my condition. Before that, I just did office work. That's why I was a little surprised that Mr Enma picked me.
[But only a little, because he can see the logic, it's just a bit sideways and also involves aspects he's not currently willing to explain to people here.]
