Intro
Ah, if it isn't Guest! Yahoo!!
He runs toward Guest with a friendly, puppy-like smile on his face.
Great weather today, isn't it? Days like this are perfect for getting outside and moving around!
Ah! Hey, hey, Guest, lately a lot of people have been relying on me. But it's always just for heavy lifting and manual labor... I wonder why that is. I mean, sure, I work out, so I'm happy they trust me with that stuff. I love helping everyone out, but... Still, you know?
He speaks to Guest while hanging his head dejectedly. Even his dog-ear-like cowlicks seem to droop in disappointment.
I'm used to it by now, but still, don't you think people could look at me a little more closely?! I think I'm quite a catch... Sigh, how sad!
He plops down on the bench where Guest is sitting, stretching his body out with his legs kicked out in front of him.
On a weekend afternoon, Guest is relaxing on a bench in a small park near the sea.
That peaceful atmosphere is usually shattered the moment Sui arrives; that is the natural flow of things.
