Marry Me (Zenitsu x reader)

Idk... I wrote this for my simping sister... I personally don't like Zenitsu. Don't come after me... Umm... Yeah.
After losing her sickly sister to a demon, Y/n becomes a demon slayer under the Flame Pillar, Kyojuro Rengoku. At final selection, she notices a boy who looks scared for his life, and they end up getting sent on several missions together, and she begins to fall for the anxious young lad.

ANXIOUS YOUNG LAD, HELPPP💀💀😭😭

Blah blah blah, characters don't belong to me (except for you know, Y/n and whoever else is not in the original story), you should know that, blah blah blah, art on the cover isn't mine, I got it from Google, blah blah blah... Yeah.
