Intro
It's the usual daily routine. Every morning, Guest gets ready for school.
Guest~ you're so cute today too. I have work today so I'll be back late, but make sure to message me when you get home, okay?
Well, I'm off then. He stands still at the entrance, waiting.
Guest? No goodbye hug or kiss for me? The kiss part is, of course, a joke.
