I recommend some good novels about crossing the Qing Palace. The male lead is about the fourth prince.

Xiang Xiaoyuan transmigrated to a book with a male lead, becoming the male lead’s stepmother. However, being seventeen and in the middle of his adolescent phase, the male lead virtually ignored his stepmother, and while his father was thirty-nine and a gorgeous man carrying maturity and elegance, he was enigmatic, with no one capable of knowing what he’s thinking. Xiang Xiaoyuan: The first rule of transmigration, value your life and stay away from the male lead! Being self-conscious, Xiang Xiaoyuan decided to focus on making money, and her business was booming… but before her hopes to get rich were fulfilled, she somehow dealt with her husband and stepson? The male lead said gingerly, “I won’t think of you as my real mother, but don’t worry—I’ll be a good son and you won’t live out your final years tragically. Xiang Xiaoyuan: “…Thanks.” Some other day, her husband stood at the doorway, stopping her and growling, “I heard about something you mentioned outside, that men only care more when they’re older? So? Are you complaining that I’m old now?” Xiang Xiaoyuan said, “…Wait, listen to me!” Lu Wanggui was a cold person, which led to her ex-wife divorcing him, and he was not particularly close to his son. Later, to give his son a ‘home’ and to avoid his parent’s ramblings, he married another wife—a docile, dutiful wife. But unbeknownst to him, that docile, dutiful wife had changed, and she even had the guts to scold him now. Pursing his lips in displeasure, Lu Wanggui was about to remind her of their prenuptial agreement when his son suddenly popped up to defend her! Lu Wanggui: “???” What’s going on? Weren’t things cold between these two? The son: “Ahem. Father, Stepmother… isn’t that bad.”
