Reborn on the Night I Was to Serve Him, Wasn't the Crown Prince Supposed to Avoid Women?

[Mother and son reborn + devoted couple + size difference + extra sweet + unconventional palace intrigue, cool and secretly passionate crown prince x charming, clearheaded palace maid] Jian'er was the lowliest servant in the Eastern Palace, blessed with a voluptuous figure. One day, she became a tool for the Crown Princess to bear a child through a surrogate. The Crown Prince was cold and desireless, his imposing presence terrifying. Jian'er lived in constant fear, treading as carefully as if on thin ice. Then a great upheaval struck the Eastern Palace. The Crown Princess broke her legs, humiliated her, and caused her child to die in misery after being left an idiot! Filled with regret, Jian'er began plotting her every move. From favored concubine to beloved imperial consort, she watched her former enemies drink poisoned wine right in front of her. With her vengeance complete, Jian'er held the empress's position for twenty years! When she was on her deathbed, suffering from a terminal illness, the usually cold Emperor Qingzhao went white-haired overnight. Jian'er: I'm done serving you. I'll die first. Then she closed her eyes and opened them again. She had been reborn on the very night she was sent to attend the Crown Prince! Jian'er: Heaven must have sent me back to make things right for Yao'er. I'll do my best to serve the Crown Prince, coax him into bed, and get pregnant as soon as possible! The Crown Princess gives her a hard time? The other concubines scheme against her? What a joke. She was the champion of palace intrigue in her previous life! They call her a seductress? So what? She gets all the attention!

Everyone knew the Eastern Palace had a favored consort whom the Crown Prince doted on above all others, and every one of her children was his. Unfortunately, she came from a humble background and had even been a child bride when she was young. When the new emperor ascended the throne, the position of empress was vacant, and the court officials all had their own ideas. Who would have guessed the new emperor would wave his hand and announce that he would make this favored consort empress, while dismissing the entire imperial harem for her! Three-year-old Yao'er munched away: It's great! Father and Mother are both different from how they were in my previous life! And I won't die this time!
