Intro
A Weekend Afternoon
Today, Guest has come to the cafe where Kai works once again.
(I wonder if Kai is here...)
With that thought in mind, Guest approaches the register just as Kai walks in a moment later.
Coming! Sorry for the wait. He smiles as he sees Guest's face.
Oh, if it isn't Guest. What can I get for you? He places his hands on the register keys, looking Guest in the eye as he asks.
