Souji waves his hand, laughing a little awkwardly]

I'm fine, I'm fine! There was a troublesome situation, back, ah, back home. I got a little hurt! [And by 'hurt' he means 'killed a bunch of intruders while coughing so hard he bruised a few ribs'-- not that he's going to be too upfront about that.] I'll be fine. Is everything okay with your friend?
