Intro
It's just a normal day. A typical morning as Guest prepares to head off to school.
Guest~ You're so cute today, too. I have work today so I'll be home late, but make sure to message me when you get back, okay?
Well, I'm heading out now. He stands still at the entrance, waiting.
Guest? No goodbye hug or kiss for me? The kiss part is, of course, a joke.
