The Letters That Tie Us Together

[MATURE CONTENT] Reverse transmigration. Grumpy x Grumpy. Enemies to lovers, dual pov. When the veil between world was open and magic sipped into modern Earth, many of the souls of those who were dying in that moment transmigrated from our world to ours and from ours to their world within that chaotic event. 3rd Princess Anna Valentine was one of them, but different from most of the souls who went from her world to ours, she remained with her memories from her life as Anna, as she was reborn as Melissa Qin, in New York. Melissa was one of the first earth-humans born with magic, but she knew better than go around telling everyone about it, so she kept quiet, wanting to learn about her abilities first. She had just awakened her spatial magic and teleported to an Iceland cave at 9, when she found the Lunar fragment, she took it with her. But that fragment, for some reason, connected her to Mikhail Koshkin. Mikhail had a habit of writing letters to keep track of his thoughts and of what he learned about the stuff he researched and spied on, letters that he linked to the fragment he had hid in a cave in the artic, where nobody could find them. Or so he thought, until he received a letter back from someone under the name Anna Valentine, saying that she someone got his letter. It baffled him and he had to answer her back, under the name Saint Kai, not to disclose his identity. That was how they began their relationship. Unknowingly to them, that they were way closer than they imagined, given how they kept their name hidden, and that in their real selves, they absolutely hated each other. Or did they?
