Transmigrated as a Concubine-Born Daughter and Secret Mistress, I Help the Young Marquis Win Himself Over

(Historical romance, transmigration, household power struggles among concubine-born daughters, a proxy marriage, love after marriage, and political intrigue)

Modern-day orphan Lin Qing transmigrates into the body of a concubine-born daughter who has just arrived at the estate. Her birth mother is dead, her legal mother exploits her, her elder half-sister makes things difficult for her, and several concubines keep switching sides, all intent on using her and tearing her apart.

With her wits about her, she refuses to be pushed around. Instead, she wins over the maids, cultivates loyal allies, acquires farmland, and makes money through trade to secure her footing.

As Lin Qing carefully investigates things step by step, she unexpectedly discovers that the Lin family plans to send her in her elder half-sister's place to marry the young marquis, who was injured in battle. Why would they pair an unmarried legitimate daughter with a concubine-born girl and marry her into the marquis's household, despite their vastly different status?

Forced into the struggle within the imperial family, she faces an imminent wedding when the young marquis returns to the capital. To her surprise, it turns out to be him!

One day, when she returned to her room, someone suddenly sprang out from under the covers and clamped a hand over her mouth.

“Don't make a sound, or I'll kill you.”

“Let me go. Better yet, let's make a deal. I can get you out of here safely, as long as you tell me a few things. Do you know the young marquis of the Yiyong Marquis Household?”

“Why are you asking about him?”

“Because I'm in love with the young marquis.” She blurted out a lie, not noticing the strange look on the man's face beside her.

Later, the two were married by imperial decree. Lin Qing thought they were merely sacrifices in the struggle for imperial power, until she saw him beneath a tree, carefully writing, stroke by stroke: “Your jade-green collar, oh, how it haunts my heart.”
