[ You would think Ouma wouldn't draw attention to incriminating things like how exhausted Shuichi is, or that he didn't get much sleep, or the fact that nobody would've known where he even was last night (but Ouma knows).

Except here's Ouma, doing the exact damn opposite. Playfully, with feigned surprise, he makes a show of acting interested in this detail as he sticks his fork back into his food to prep another bite: ]

Huuuuh? Just what were you up to last night? Nothing shady, I hope!

[ He twists his fork around in his bowl as he speaks. ]

There's that rule about going out, y'know. It's pretty stupid, since nothing interesting will happen if everyone follows it, but I didn't take you for the type to break it. [ A beat. ] You didn't, right?

[ Taking another bite..........

This all too natural pattern he slips into -- attempting to control and lead the conversation while stirring shit around -- might be making him feel more comfortable himself overall. He knows it'd drive him insane to just sit here quietly and eat. Not his style. ]
