Secret garden kny

I got this idea from off youtube. "Hashira react to "Secret Garden" -ft. Hashira - not OG! (not Original) ☆Details☆~ MY AU (alternative universe) So Tanjiro and Nezuko's family still remains D but instead of just Nezuko being exposed to demon blood and turning into a demon, so was Tanjiro. Confused? let me explain- the reason Tanjiro became a demon, was because in my AU Tanjiro stayed at home and didn't go down the mountain into the village, and caused him to end up like Nezuko, after they're family was...you know. BUT Nezuko doesn't know that Tanjiro is a demon too! HEHE!! "PlOt TwISt" ☆STORY☆~ Though, Tanjiro woke up before Nezuko did and ran off, when Nezuko woke up she just wondered into the mountain and yet, came across her brother. (Tanjiro) (also ur Tanjiro...or Nezuko idc) ☆The rest of the story is in the opening below☆
