After Switching Places with the Cold Palace Princess, I Went Off the Rails

Dual female leads + Swapped identities + Devoted relationships + Coming-of-age story Xiao Cao, later renamed Bai Wanan, takes the princess's place as a hostage in the enemy kingdom and is dumped in a brothel to work as a servant. One disaster follows another. If keeping her head down won't keep her alive, then she'll go wild and be the boss! Gifted with extraordinary talent, she masters the art of dance and performs atop the rooftops on the streets of the capital, captivating the entire city with a single dance. Princess Anzhen, later renamed Ning Rouxin, survives by passing herself off as a palace maid, only to be sent to the privy to haul waste. But fate refuses to leave her alone. If enduring humiliation just to survive won't let her live in peace, then she'll lie low and kill! Using floral art as a cover, she takes out her enemies one by one, leaving her hands stained with blood! Neither heroine is a good person in the traditional sense. Ning Rouxin in particular is a villain through and through!
