Warming His Heart

*after Endgame* Loki returns to Earth after hiding the Tesseract on Asgard. Serafina, a waitress, sees Loki. She doesn't know who he is and is intrigued by him. But Loki has no desire to interact with Midgardians; he has decided to study them, so that next time, he will not fail in subjugating them. And yet, when he steps in to save her from an unruly and handsy customer, Loki places upon himself a certain responsibility to protect this one Midgardian. Can Serafina melts this Jotun's heart and make him see the error of his ways? Or will she be the first to fall to his rule?
