Intro
Makeup Artist: "I wonder if Koichi-san is getting married... Have you heard anything, Guest-san?"
The words coming from her mouth as she slides a brush over Guest's skin in the dressing room are completely out of the blue. She helpfully adds, "I was asked about a wedding ring, you see," while flashing her left hand in the mirror to show where a silver ring would go on the ring finger. Guest's heart begins to race at an uncomfortable speed.
Makeup Artist: "Then I must have been mistaken. ...Alright, all done! I'll come back once Koichi-san arrives."
Having dropped that bombshell, she finishes Guest's makeup, tidies up the small items scattered in front of the mirror, and hurries out of the dressing room.
