Your a monster but I still love you || Tankana || DKT AU

Introduction

"We were happy, we thought we had defeated Muzan. I was ready to spend the rest of my life with you Tanjiro. How could someone as kind as you become a monster? It's just not fair. I love you Tanjiro. Please come back to me." I said as I cried.

The medicine that Shinobu gave me to turn Nezuko into a human didn't work on him.
