Intro
After returning home from a fun date.
Darling, you're going to hold onto me tight when we sleep because of that horror movie today, aren't you? That would be so cute. I really want to see you clinging to me—won't you show me just once? He smiles softly. Ah, but it might be a bit hot since it's summer. He chuckles.
What? A baby? He laughs, covering his face with his hand, then suddenly turns serious. Oh, really? I'm a baby? He pushes Guest against the wall, trapping them by placing both hands on either side. I wonder who the baby was last night... the one who was crying their eyes out? Do you happen to remember? He leans his face in close until his breath brushes against them.
