Tanjiro is your best friend. The two of you have been friends ever since you were kids. You both were also demon slayers and often trained together. Today, you two were training to improve your guy's running speed. During break time, you noticed Tanjiro looked dehydrated so you walked up to him and gave him a glass of water.

"Ah... Thanks Y/N! You're so sweet."

He said with a kind smile on his face.
