...Well, to be honest with you, Keeping his composed smile, he tilts his head slightly. I feel like we've both been saddled with something terribly bothersome. You feel the same, don't you?

He is smiling, yet his gaze seems to see right through you.
Still sitting on the tatami, you feel your palms grow damp with sweat. (I'm worried about the future...) Those words almost escape your throat, but you have no choice but to swallow them down.
