Su Qinghuan, the abandoned concubine in the cold palace, just "awakened" and learned that she was the cannon fodder NPC in the palace battle drama. In order to save her life, she seized the only opportunity and signed a one-year contract marriage to Xiao Jingyuan, the most effeminate and least favored idle prince in the palace.
They wanted to take advantage of each other and live a stable life, but unexpectedly troubles came one after another: local gangsters tried to extort money, prejudiced courtiers made things difficult for them, and hidden traitors even regarded them as a thorn in their side.
Su Qinghuan went against the grain and played tricks, confronting gangsters, fighting prejudices, and finding traitors, causing trouble. Xiao Jamyuan seemed to be gentle, but he always cleared the obstacles for her in the dark.
When the contractual relationship gradually deteriorates, the secret of the NPC's awakening is also at stake. In the treacherous palace battle, can the two go from using each other to fighting side by side?
