"Excuse me, do you happen to have a lighter I could borrow?"

A familiar voice speaks up beside you, every voice was familiar at this rate as you had been locked in a prison with the same 10 other prisoners and 1 guard for god knows how long at this rate and even if you didn't talk to a prison you knew their voice off by heart at this point. You look up to see a face you had seen a thousand times before, you and Shidou had never actually chatted just merely acknowledged each others existence.

Even if he was a prisoner, he was still respectful. Despite being quite taciturn.
