[Both leads are devoted only to each other, both are strong, political intrigue, transmigrate into a book, the original character has children, but they aren't hers.]
After transmigrating, Sang Ning becomes the most notorious princess in Great Xia. She not only bullies the common people and flouts social order, but also forces herself on the male lead and is the worst child abuser of them all.
When she meets the three little villains and sees their clear, innocent eyes, Sang Ning is relieved she arrived early. The children haven't turned into villainous powerhouses yet; otherwise, her days would be numbered, and she'd end up dead in the wilderness.
Sang Ning resolves to cling to the powerful and devote herself to being a kind, loving mother.
At first
The three little ones: "Let us examine ourselves three times a day. Has the bad woman humiliated me? Bullied me? Hurt me?"
Later
The three little ones: "Mother is wonderful, Mother is the best! I'll smash my head against a wall for her! You bullied my mother? You're dead!"
Sang Ning devotes herself entirely to the children, until one day the Imperial Preceptor kidnaps her.
The man pins her hands and corners her against the wall, demanding in a low voice, "Do you want me or the children?"
Sang Ning: "The children."
The Imperial Preceptor: "No. You want both."
