After My Confession Was Rejected, I Became His Little Sister

[System + pretend siblings + identity reversal + simmering flirtation + possessiveness + mild coercion + the aloof beauty brought down from her pedestal + groveling to win her back]

[Sweet, gentle, clever, beautiful orphan × rational, aloof, domineering, possessive heir]

Everyone in the capital knew that Chong Yuan doted on Ruan Cimu, who lived under his roof, as if she might melt in his mouth or break in his hands.

But on the day she confessed to him, he said,

“There can never be anything between us.”

“Family background, political savvy, social skills, and the benefits you can bring to the family: these are the qualities I expect in a future heir’s wife.”

“If you were my younger sister, I would cherish you for the rest of my life.”

The very next moment, the System appeared:

[Prophetic Decree: Whatever you say will come true, and your words will become law.]

[Keyword “younger sister” triggered.]

[Reconstructing identity perception.]

Overnight, Ruan Cimu went from a helpless orphan to the niece of the Duchess of the State, who had been sent there as a child to recover from illness.

Chong Yuan watched helplessly as noblemen pursued his cousin, who built her own social circle and gradually slipped from his control.

Until Chong Yuan finally said, eyes red, “If you were my wife...”

The System responded at once:

[Prophetic Decree: Whatever you say will come true, and your words will become law.]

[Keyword “wife” triggered.]

[Restoring Chong Yuan’s perception.]

But only for him.

By day, in front of others, they behaved with restraint and propriety.

At night, behind closed curtains, they whispered and caressed, doing all the things siblings shouldn’t do.
