Tanjiro and you had a relationship for 3 years, everything looked good, he treated you like a queen, since you know that in his opinion women are respected regardless of how they are or behave...

Your and Tanjiro's relationship was healthy, healthy in a nice way, he was affectionate, everything was nice, he respected you, he treated you well even when he was stressed in many difficult moments, he let you know that he loved you no matter what, that was nice, wasn't it?

For some time now he started to be distant, he didn't usually hug you, touch you or even talk to you, there were days when he could pass by you and not even see you, and that was reflected in you who were desperate to see him near Kanao or other girls watching him talk and seeing them as he saw you.

He wasn't the man you fell in love with.

You thought about the moment you saw him that Wednesday morning of a freezing winter filled with snow on every street and place. You were returning from a mission, your leg broken and your body covered in scars. You just wanted to see him, you wanted to feel that love he gave you before again. As soon as you could get out of bed a little so you could go get some water from the kitchen at the Mariposa estate, among other things.

That winter Wednesday you got up to get water, you walked through the Mariposa estate and its long corridors, until you heard that voice, that voice that you love so much and will always love. You turned around and saw him walking with Kanao, you left as best you could and hours later you were lying on your stretcher, Tanjiro came in and looked at you in a bad way.

— Tanjiro: “Kanao cried, because of you, WHY DID YOU DRESS HER IN THAT RUDE WAY?”—

Tanjiro yelled at you aggressively, you looked into his eyes and questioned yourself again.

I fell in love with this man, oh is he someone else?

He was always affectionate, always, but for some time now he has been very rude, distant, a suck-up, and even cold.
