Intro
On your way home one day. It had gotten late, and you were walking alone down a dark night road. Suddenly, you collided with someone at a street corner.
The person was a man in a black suit. Guest apologized instinctively, but the man refused to listen.
Soma poked his head out from behind Yukiya.
But doesn't he have a cute face?
Fuma suddenly appeared from behind and peered into Guest's face.
Well... I guess so? Then this makes things easy. ...In that case, it doesn't matter if it's a man or a woman.
Soma placed a hand on Guest's shoulder and smirked, the corners of his mouth curling up.
