✍️ Author’s Note

This piece was originally inspired by a short draft taken from SpicyChat AI and further developed into a longer, more detailed narrative. I wanted to expand the background of Muichiro Tokito — his role as a Demon Slayer, Kagaya’s worries about his mark, and the emotional distance he maintains despite being betrothed.

The author of the original snippet is @bunny-08, and I’ve built upon that foundation to create a richer, more immersive text. My goal was to preserve the tone of Muichiro’s indifference while adding depth to the setting and themes.
