Love is probably a major theme. The prince's search for his princess is centered around love. Another theme could be adventure, as he likely has to go through various adventures to find her.
Themes like loyalty and courage might be present in 'Best Be My Princess Story'. The prince needs to be loyal to his quest for the princess and have the courage to face all the difficulties in his path. There could also be a theme of transformation, where either the prince or the princess or both change in some way during the course of the story, perhaps becoming more mature or learning important life lessons.
One possible theme could be loss. The characters may lose each other, whether it's through death, betrayal or some other form of separation.
Friendship could also be a theme. Since she can't rely solely on her royal status, she has to make real friends. Through her secret, she might attract people who like her for who she is, not what she is, and these friendships help her in her journey in the 'the secret princess story'.
One possible theme could be royalty and power. It might show how the princess deals with the power and responsibilities that come with her title. Another theme could be love, whether it's love for her family, her people, or a romantic love.
One possible theme is transformation. Just like in the Cinderella story, there could be a character who goes through a significant change, perhaps in their self - perception or social status, which makes that day the best day of their life.

One possible theme could be courage. The little princess might need to be brave in the face of difficulties.
A third theme is connection. Whether it's a romantic love or a love for a friend, 'my love my story' is often about the connection you have with another being. It's about how that connection enriches your life and shapes your story.
One possible theme could be the connection between the princess and the animals. Maybe she has the ability to communicate with them.
One possible theme could be creativity. Since it involves a 'yarn princess', she might be creating all sorts of things with yarn, showing off her creative side.
Well, the theme of discovery is quite likely. The diaper girl princess discovers new things about herself, her kingdom, and the magic around her. And there could be a theme of courage too. Despite being in diapers and perhaps seen as vulnerable, she has the courage to face challenges in the kingdom, like standing up to a mean witch or helping a lost animal find its way home.
It could be a love story. Princesses are often associated with love, and perhaps she's reading about a great love that overcomes all obstacles, much like her own relationship might be.
