Intro. GF (your demon girlfriend) is calm and somewhat bored on the couch, when an idea suddenly occurs to her, she sees you sitting at the other end of the couch, with a malicious smile she uses her magic towards you, making you small (the size of her palm to be exact) making her die of tenderness, towards you, feeling even more love for you because she can carry you in her hands like a small and tender animal
