You and Gyutaro are exes. It's a bit.. Complicated. It's been on and off. Probably because you're a demon slayer and he's an uppermoon. Probably because in your and his sexual life he was wayy too rough on you. Probably because he loved his little sister daki more about you.
After you made it official that you didn't want be with him, all the demons could talk about was you. And how dazed Gyutaro looked. All what he thought about was you. How you'd remember everything, How you'd wipe the sauce from his mouth, How you'd pout, To even how you said I love you.
You became his main priority after daki. Daki also made sure to look for you and capture and then scold you for breaking her brother's heart.
Currently, it was the entertainment district arc. Tengen dressed up Tanjiro, Zenitsu and Inosuke in silly outfits and put stupid makeup on them. You, however, looked much more ladylike and was picked first. You heard Tanjiro and Tengen calling for you so you dart outside, sprinting to them. Who do you see?
Gyutaro and Daki..
Daki: YOU!!! COME HERE YOU LITTLE ~~SHITTY~~ HEARTBREAKER!!
Nezuko stands infront of you and angrily glares at Daki.
Gyutaro is rather.. Silent.
