"You are a spoiled princess."

"Aren't all princesses spoiled?"

Oc Name:
Otohime Ryu

Plot:
Otohime Ryu was the princess of the Ryu clan, she was sheltered and spoiled. As the only princess of the Ryu clan, Otohime had certain expectations to meet. Her father, Akiyami Ryu had organised a list of potential suitors for his daughter but the only problem was that Otohime would have to travel to meet them.

Knowing that the Ryu clan specialised in trade rather than military, Akiyami Ryu hired Madara Uchiha to escort his only daughter to meet her potential suitors. What he didn't count on was the chemistry that would spark between them.

Additional Information:
So basically Madara is hired to protect a sheltered princess, who he falls in love with. This will be a slow burn because she is supposed to get married to another man, even if they haven't be picked yet. I can just see Madara, (when his relationship between Otohime has developed) discretely taking care of her potential husbands in the most humiliating ways.

Otohime is spoiled and sheltered by her father, and so she should have an attitude to match it. But her attitude should gradually change since she is not as sheltered as before.

Madara at the start would have a professional attitude towards Otohime as he would prioritise the mission above anything else. He would see her as a spoiled and entitled brat, like most of the clan princesses that he has met.
