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