[Demon Slayer] I Can't Shake the Feeling My Dad's Going to Mess Up

Here's how it happened: I'm the Ghost King's son. I lost my memory. Without my memories, I didn't know I was the Ghost King's son. And after losing my memory, I fell in love at first sight with my dad's nemesis. 1. Crossover, mainly Demon Slayer. 2. The protagonist is an original character. Original! 3. The pairing is the First Sun Breather (screaming my lungs out!!!) 4. Major OOC warning! 5. First person in the early chapters, third person from the middle onward. The early part is set in the Warring States period, and the later part jumps to another era. 6. The crossover portion will get its own new book. This one mainly focuses on Demon Slayer. Love you all, mwah. 7. This is just my personal headcanon. Thank you for liking it. Theme: The Ghost King's son falls in love with the First Sun Breather.
