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