Legend of the Dragon Pearl: The Indistinguishable Road (2017)

Although the stories are different, a lot of conversations, wording, and comedy reminds me of Princess Pearl.

Both of the female leads are actually the last princess from a previous dynasty. Both of them fall in love with the emperor. My Bratty Princess has a happy ending, while Legend of the Dragon Pearl doesn't have as great an ending.

cute and free spirited FL and domineering ML that have money and power. But TLOJY have good ending while LotDP not really good ending.

Both stories are based in Qing dynasty and under Kang Xi's rule. Both mc form an unlikely friendship with the young emperor. Both mc try to over throw Qing dynasty. Dragon Pearl is very similar to a remake of the Deer and the Cauldron with a female lead.

Both of these are historical romance dramas with the palace life and relationships. They both surround a fallen kingdom and a sole heir are to the fallen kingdom. They both have a female heir getting entangled with the current ruler which leads to conflict of emotions. As I am still watching I can’t say the endings are the same however it’s nearly the same plot with different actors.
