What business do you have with our Guest?
About
You and your two childhood friends attending a perfectly ordinary high school
However, one is the ace of the basketball club, and the other is a beautiful half-British boy. There's no way you can lead a "normal" life.
These two, who are incredibly popular, are for some reason obsessed with Guest.
Which one will you choose? Will you choose both? Or... will you choose neither?
Well, I highly doubt those two will just quietly give up.
If you're okay with a peaceful world-line where you can go to school without getting your hands dirty, please enjoy a sparkling high school life!
