So this is the real mystery, isn't it?
I mean one day you wake up and realize you have the entire world at your disposal, the hottest Prince is your fianc, all the comforts are an order away and to make matter better, even a caring family. A family that is so overwhelmed with re-uniting with you after 16 long years that they overlook all your immaturity and mistakes, fulfill all your demands and put up with your tantrums. They have sworn to do right by you, and give you everything you ask for - except your old life, of course.
Then why won't Moniya just embrace it all? Why is she trying so hard to hold on to her chawl lifestyle, Chikki and Soni and most importantly Akash?
Because that is all she has left of her identity. Think about it. A girl who has just lost her father (figure), who has no place to call her home cuz she has been on the move all her life, and who's only souvenirs growing up as a nomad have been the colorful swearwords and the wide variety of cuisines she enjoys.
On some level, coming to Mumbai was like finally finding a home for Moniya. The very first episode showed her describing the odd familiarity she felt with the city. It was here that she finally decided to go out and get a job, it was here that she formed close alliances and it was here that saw herself settled down for a good while ahead.
No wonder then that she doesn't want to change, no wonder she won't give up her ways, no wonder she will go to any extents to fight for her right to stay the same. Because changing into the Rajkumari and giving up these seemingly 'bad habits' equate to giving up her very essence for Moniya.
Similarly giving up Akash would mean giving up her ability to make decisions. He is, along with Sonu and Chikki, the last remnants of her last 16 years. They were her first 'family'. They made her feel loved and wanted as no doubt her previous friends had done but they were the last ones she didn't leave willingly. They were ripped away from her and this is what makes them dearer to her.
She maybe a princess now but she is still essentially a chawl girl, a self respecting one, who doesn't even consider a guy like Udayveer a match possible. She is just a girl who loves a boy who is too good for her (in her opinion). This is why she cuts corners, makes compromises and goes out of her way to appease Akash. Because she genuinely believes he deserves better. Because she is no princess, she is just a jhalli girl who can't speak in English and never even went to school.
This is why, she is trying against all odds to hold onto the dreams, hopes and plans she had invested into finding a stable home, into finding love. Akash for her is a means to achieve that dream. While she may yell and shout as much as she wants that she loves Akash, the truth remains that she is more in love with the idea of stability and home that Akash promises.
Come what may, Moniya won't want to give up her relationship with Akash. As short and new as it maybe, giving up on the relationship won't just mean dishonoring her words, and breaking a commitment she made but also giving up on 16 years of her life and everything she knows.
While DS and the entire royal clan might slowly and eventually succeed in making sure she looks and behaves like Rajkumari Manyata, UV, it seems, might have a greater task cut out for him.
