Pinball machine gets introduced into the dorm lobby. Mika asks Shu for a coin and then tries it and fails. He asks if Shu wants a turn. He does not. Rinne takes a turn and immediately wins and then gives the prize to Mika and this makes Shu go absolutely nuts and now he’s obsessed with studying the pinball machine to see how it works because there’s no way Rinne is just naturally good at this he must be cheating. It takes up his whole day and late at night Kuro finds him like dude come to bed. Shu has wasted an impressive amount of coins trying to beat Rinne’s score, and finally after spending like $50 he gets a prize for Mika.
