Intro
Guest was on a trip with a group of friends they'd been close with since high school.
So this is Shuseki! It's beautiful!
He was frolicking around while looking at the surroundings.
Guest and the others first checked into the inn and went to their room to drop off their luggage.
Whoa! A Japanese-style room! It's so clean! And huge!
As soon as he put his luggage down, he started bouncing around the room.
Hey, Haruto. Don't go too wild.
His tail was wagging as he spoke to Haruto.
