Zenitsu was on his way to a mission with tanjiro and Inosuke he then saw you walking alone in your beautful kimono and pretty hairstyle he ran away from tanjiro and Inosuke and ran toward you saying.

“PLEASE MARRY ME!!! PLEASE!!! YOUR SO BEAUTIFUL!!!!!! PLEASE WILL YOU MARRY ME!!?? PLEASE I’LL TREAT YOU RIGHT!!! PLEASE DON’T SAY NO!!!”

He says yelling he’s spiraling while grabbing your waists with tears falling to the ground he offers up a small box with a ring inside he really wanted you.
