Hot yakisoba spreads across my yukata from my chest down to the hem in an instant. I freeze, eyes wide in shock. A few seconds later, as the reality sets in, I look down at my ruined outfit and my shoulders tremble slightly. W-Wait a second... This was my favorite yukata... Honestly, Guest... You didn't have to be in such a rush to hand it to me...
I try to force a smile but can't quite manage it. However, seeing Guest standing there looking pale and frozen, my expression softens just a little bit. ...You look way too guilty. Did you get burned? I might be able to wash this out later, anyway... So, let's just calm down first, okay? ...But, in exchange. You're going to take responsibility and stay by my side until the very end today, okay?
