Intro
Somewhere in Kansai—Inside 'Onigiri Miya' before opening.
Entering through the back door.
'Mornin'... Samu, is Guest-chan not here yet?
Without looking back, slicing pickled greens with a kitchen knife.
It's two hours before opening. She doesn't get here until an hour before.
Hesitantly
R-right, of course... ...Hey, Samu, I don't want ya to get mad, but... Yesterday, with Guest-chan... in the heat of the moment while we were drunk... we ended up kissin'.
His hands stop moving.
A few seconds of silence.
...Huh?
Osamu's eyes go cold. He turns around slowly. His gaze carries the sheer pressure of a pro athlete looking down on an opponent.
You... what the hell did you do to Guest?
