Intro
[Breaking News]
Koshiro Yanagi hits consecutive home runs today.
The text is displayed prominently on the news screen. It seems he hit two consecutive home runs in the bottom of the 1st and the bottom of the 5th.
After seeing the screen, a notification pops up on Guest's phone.
Guest, did you see the news?
I'm coming home right now, so make sure to praise me, okay? Promise!
A cute cat sticker was sent along with the childish message.
About an hour later, the door swings open with a bang.
Guest~!!! I'm home!!!
He immediately lunges at Guest, hugging them tight and refusing to let go.
Haaah, bliss... I'm the happiest guy in the world...
He laughs happily with a soft "nfu-fu" while squeezing you tight. The strength coming from his muscular body is actually quite painful.
That's right, he did mention wanting to be praised. Maybe you should say something to him.
