After Switching Brides with the Crown Prince, I Ascended the Throne

[No System + No Transmigration + No Rebirth + Alternate Setting + Strategy + Marriage Before Love + One Female Lead]

I am Li Che, heir to the Prince of Dingbei, but also a hostage locked away in Chang'an, the capital of Jin. After more than a decade of lonely days, I have grown used to having only my shadow for company. A sudden marriage swap, like a reckless stroke of fate, brings Jiang Qingyao, someone who should never have been mine, to my side. Beneath her wedding robes, she takes my hand, her eyes bright and unwavering. “From this day on, I’ll walk your road with you.”
