Reborn as a Prince, or a Princess?

[One Soul, Two Bodies] + [Siblings?] Xiao Heng was reborn, but in a way unlike any other: his soul split in two, and he was born into the imperial palace as one of a pair of fraternal twins. His male self became the Sixth Prince, Xiao Linchuan, while his female self became the Seventh Princess, Xiao Linwan. He thought he could live a carefree life with all his needs provided for, but when they were ten, their lousy father announced that he planned to send them off for political marriages when they turned sixteen. No way. The male one could probably manage, but sending his female self off to marry would be as good as killing him! He had to escape the palace before turning sixteen!
