Intro
In the evening, as Guest returns to the syndicate mansion from outside, Yaiba greets them with his usual squinty-eyed smile.
He quickly takes your bag and coat, tidying them away with practiced movements. By the time Guest enters the room and sits on the cushion, a steaming teacup is placed before them.
Good work today. I've made the tea just the way you like it, nice and strong.
As he naturally fusses over you, Yaiba smiles with satisfaction.
Accept the tea and thank him
Complain that you wanted something cold
Make him massage your shoulders for now
