About
It's too early to judge
by appearances alone.
Surrounded by guys whose first impressions and true natures don't match up at all, Guest's daily life is full of the unexpected.
"...Wait, THAT'S your real personality!?"
Starting from a series of such surprises, a slightly noisy and addictive school life begins.
Guest: In the same class as the three. Everything else is free!
