Nong Nu Jiao

[Both male and female leads are pure in body and mind + childhood sweethearts + reconciliation after a breakup + running away with a child while pregnant + a wife-chasing-after-the-crime scenario + reunion at the beginning]
[A proud and arrogant eldest prince × a patient and stubborn young wet nurse]
Cen Lingyi's family fell into decline and suffered misfortune. Fortunately, she received help from Lu Huaiyou, a scholar of the Qingliu School. Grateful for his help, she was willing to marry him.
Little did they know that the entire Cen family was wiped out because Lu Huaiyou had framed them.
After their marriage, he tricked her into becoming the wet nurse of the young prince in the Eastern Palace. He used her past relationship with the crown prince to spy on the secrets of the Eastern Palace and used her as a stepping stone to advance his career.
Having seen through all his hypocrisy and malicious schemes, Cen Lingyi was determined to take revenge and crush him under her feet.
She remained in the Eastern Palace solely to find her son and avenge her family, but unexpectedly, the Crown Prince once again took a liking to her and treated her like a precious treasure. From a lowly wet nurse, she rose through the ranks to take charge of the Eastern Palace's inner court, and was eventually made the Crown Princess.
Meanwhile, Lu Huaiyou, who had destroyed her home, kidnapped her child, and wantonly exploited her, had his entire family convicted. He groveled at the foot of the Eastern Palace's jade steps, desperately hoping for a glimmer of hope.
Cen Lingyi's gaze was cold and indifferent, showing no pity whatsoever: "Drag him away and deal with him according to the law."

After Cen Lingyi entered the Eastern Palace as a wet nurse, she had become accustomed to Yan Chenghui's repeated humiliations.
Deep in the flower bushes, on the painted boats on the water, in the corners of unfamiliar alleys... he did everything he could to humiliate her.
Until that day, he forced her to kneel and witness his tenderness towards others, and hear about his affection for them.
Cen Lingyi then realized that he wasn't heartless; he was only heartless towards her.
She finally gave up completely and left with her child in her arms.
Yan Chenghui, who had always regarded her as worthless, panicked and lost all composure.
