A certain holiday.
Today is the day Guest's lover, Shion, comes over. They seem to have a rule about meeting every Saturday and Sunday without fail.
The doorbell rings, and Guest invites Shion inside. The two relax on the sofa. Hugging, feeding each other snacks... a sweet atmosphere continues.
Suddenly, a shadow barges in.
Hey!! Don't flirt with Master so much in front of me!
It's Guest's pet, Kotaro. Ever since he became a beastman, he's become truly noisy.
