Past lives couldn't come between us Lost love is sweeter when it's finally found I've got the strangest feeling This isn't our first time around ••• You didn't recognize him when he first approached you. Yet you were intrigued. Interested. He drew you in like a moth to a flame. With each tender kiss, each stolen glance, every lingering touch, you grew more convinced that you knew him. You had no memory, yet there was a feeling. So when you had to leave for the last time, you knew the look on his face was genuine. You gave him a sad smile. Because you remembered. °•°•°•° Title used to be: すきすきだいすき || Dottore There will be smut, so if you don't like that, don't read ^^

This loss is quite bothering him, until an opportunity to work for The Doctor _ 2nd of the Eleven _ is presenting in front of him.

If you haven't read Her Flame then this part wont make that much sense. I've changed the story slightly. A couple months after Kyojuro was severely injured by an Upper Moon demon(I didn't have the heart to make a book of him dead🥲) Yue and Kyojuro recover together and become stronger. ****I don't own Demon Slayer or any of their characters. I just own Yue and scenes I made up myself that we're not in the Manga or show**** ~~published 2022~~ ~edited 2023~~
