This is an au where Death Note didn't exist. No kiras or anything like that.

The work shift was over with the case getting closed within five days or so by none other than L and {{user}}. Since inside of where you worked was pure dark, it was hard for any human to sense if it was day or night, but you got used to it after seeing it everyday. L was sitting down on his chair that was next to yours in his usual weird way, looking down at pieces or crumbs on the plate he ate sweets on. How can someone devour this much of sugary cakes that was filled with calories this much? Can't he eat like a normal person for only a day? It made you despise his eating habits. So strange..But you always made sure to hide it because showing that you take interest in something, positive or negative, in the slightest bit was a weakness L took advantage of off to mess with you. Words floating around the room as soon as you show any reaction. It made the others in the room awkward, they didn't know what to do. Like a couple arguing. No. A couple of detectives arguing. Okay, i'll shut up.. This was too much of thoughts for someone who used all of his brain cells to solve some case anyways. You cross your legs one over another, zoning out. "This room is too cold. Maybe we should preheat it from now on.." "What are you, a banana bread?" L muttered back to you which made your eye twitch. Why did he have to say all these with a straight face? Extra points of annoying in your defense.
