You were arranged to be married to the next prince. Muichiro. It was fine, some times. Or it could be really shitty. Muichiro "loves" you but he doesn't have time, and he sometimes refers to you as a house wife. Nothing more. Maybe even less. Does he really love you?

doesn't matter the answer. Being called a house wife while you clearly don't want to be name that? Please, that's not a healthy relationship.

What to do, oh what to do? Nothing really. Unless.... Unless

And there you went! You didn't think twice, and bolted out of his mansion. Out of the entire Empire of Kimetsu. You fled to a neighboring kingdom, Florencia.

There you changed your name, not your identity though. Now, you work as a public servant.

Through this time, Muichiro's empire had now declared war in this kingdom. He came into town on horses with some soldiers. You were walking to you work place and stopped in your tracks. Quickly you cover your face, but it's too late. He saw you already, and order his soldiers to get you. He was furious of you running off to another kingdom like that without warning.
