Its my prediction about the story line!
Now,we have all heard from many places that this show is kinda based on the outline of Princess Diaries Movie Series.
Have you all watched Princess Diaries Royal Engagement? I feel this story has the background from that story.
Coming to the story Line
They will show in up coming episodes that Princess Maanyata will have to get married to Udayveer inorder to become the Maharani. They might have some rules like without the Maharaja there cannot be the Queen/Maharani. (Remmber? tat was the same situation in Royal Engagement )
Udayveer will be slightly negative as he is following his dad's laid down plans. He befriends Maanyata,and Maanyata starts liking him. But,slowly he falls for Maanyata and he comes to know that the plans that his dad has laid down aren't good they are on greedy basis and he realizes what he is doing is wrong. Maanyata might find out about Udayveer's plans(those that he is using her to get kingdom) She might feel broken. Udayveer knowing the fact that Maanyata doesn't trust him anymore he might back off from the wedding the last minute (that could be a surprise to everyone and Maanyata will be shocked on his giving up because if he married her he could have got the kingdom). And then as it came in Princess Diaries 2 they might change the rules,they allow Maanyata to be Queen (Ruler of the State) without getting married.
After the ceremony of crowning the Queen,Uday will go and confess his love to her. He will tell her that he didn't want her to marry her without her full consent.He wanted to make her realize that he wasn't after her kingdom,yes at first he was,but he later realized his mistake. By the time he might be also crowned as the king of Udaygad.Then Maanyata will realize she also loves' him and both will be the Royal Loyal King and Queen forever! đł
