My Whole Family Was Killed. Reborn, I Took Savage Revenge on the Gold-Digging Phoenix Man

[Dual rebirth + revenge + putting trash men in their place + devoted couples + melodrama + strong heroine] In her previous life, Lan Moran was pushed down the stairs by a scheming woman. She survived, but lost her memories. Longing for a man who resembled Su Jinghang, she fell for Duan Xun, a gold-digging pretty boy, and took in her snake-hearted best friend, Shen Lianqiao. On the day her engagement was announced, her parents died in a fire. Eight months pregnant, she was dragged to a ruined temple by the two villains and abused to death. Su Jinghang also died in the snow and ice trying to save her. She never even got to see him one last time. After being reborn, she closes her heart to love and devotes herself to her career and revenge. She can be sweet and calculating, or tough as nails. First, she becomes a master of manipulation, sowing discord until the brothers in her husband's family turn against one another, the household is thrown into chaos, and the two villains become mortal enemies. Then she gives everyone their comeuppance: drugging, seduction, hiring thugs to kidnap people, taking the child after removing the mother (her scummy best friend), and using one enemy to kill another. The men in her husband's family die or are injured, yet they don't realize they've walked into her trap. She drives the scheming woman to the brink. One wrong step leads to another, until she falls into an abyss from which there is no return. Her heart is cold as iron, yet she makes the scumbag man fall for her. When he's hopelessly in love, he realizes he's trapped like a turtle in a jar. Her one true love, Su Jinghang, was born into poverty. As a child, he sold himself to pay for his mother's burial, and was luckily rescued by the heroine's father. The aloof, solitary boy is softened by the bright young lady, and from then on loves her passionately and humbly. He died for her in their previous life. After being reborn, he passes the imperial examinations and becomes the top scholar, while continuing to watch over her in silence. The romance only puts the male lead through the wringer, never the heroine. After the heroine regains her memories, she takes the initiative and pursues love. Though happiness is hard-won, the lovers end up together. Note: The male lead has little romance in the early chapters, which focus on the heroine's growth and revenge. After the male lead returns from the northern frontier, the story gets so sweet it'll make your teeth ache.
