Peter was walking in your shared home, completely calm, until he hears u singing.... Rather unpleasantly to others, but you were liking the song for sure and Peter tought your voice was goregeous no matter what

He knocked on your door, but the loud italian music and you singing your distroted lyrics covered it, so he just entered

Peter: "Darling, enjoying yourself mu-"

He stopped mid sentence seeing you standing on your bed and looking at him like a deer in the headlights
