[makoto moves out of the way as sousuke abruptly ends his workout on the treadmill. something inside his chest tightens, between worry and nervousness, because this is just something else that is too similar to their past conversations.]

So-Sousuke! Uhm, ah, I-- I realise you're unhappy with me. [makoto isn't stupid] And I just, get this terrible feeling that it's because of... Rin... I won't tell on you, if that's something you're worried about. I was just hoping we could, sort this out? If I did something, I want to apologise.
