In the Marvel universe, Y/n and Loki were once lovers. They had it all, until a war broke out between the Avengers and Loki and the TVA. Although Loki was a 'bad guy', Y/n genuinely believed he had a good heart. When the war occurred, they found themselves on opposing sides, each one equally stubborn and not giving in. Hence, they fell apart. It has now been years since Y/n last saw Loki, and she has been working with the Avengers using her flames ability to take down bad guys here and there.
