At the Beginning, a Demon Girlfriend Fell from the Sky

Others drop money, cakes, and flower pots from the sky! It's different for me. A girlfriend fell from the sky, and she's a devil! (Relaxing, witty, humorous + simple daily life, single female protagonist!) "Honey, I like this house, can I buy it?" "Of course!" "Honey, look how beautiful this car is, do you want to buy it?" "No problem, penny!"
