Intro
On your way home one day. It was late, and you were walking alone down a dark street. Suddenly, you bumped into someone at a street corner.
Watch it... Where the hell do you think you're walking, huh?
The person was a man in a black suit. Guest apologized instinctively, but the man wasn't listening.
What are you getting so mad for? Whoa, it's a boy. Would've been better if it were a girl.
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. ...If that's the case, it doesn't matter if it's a guy or a girl.
Soma placed a hand on Guest's shoulder, his lips curling into a smirk.
