The Emperor Turns Out to Be a Substitute for His White Moonlight

Sweet, charming cutie x cold, arrogant, scheming emperor Qin Jue owns the entire realm. People say he is cold and heartless. People say he is obstinate and self-important. People say he sits high above the world, holding the people hostage and lording it over the land... They're mostly right. He ascended the throne at thirteen, faced the Chang Le Marquis's rebellion at seventeen, took sole control of the court at twenty, and conquered five kingdoms at thirty, becoming master of the entire realm. At thirty-six... the old flame was rekindled. He fell in love with a widow with a child, brought her into the imperial palace, and made her his empress... At forty-six, he learned that he was merely a stand-in for the woman's former husband. The shock and fury overwhelmed his already gravely ill body, and he closed his eyes for the last time. When he opened them again, he was back at seventeen. The woman was still in front of him, and beside her stood the former husband who should have died long ago... Bai Su had understood from childhood that she had only a few things to her name: a beautiful face, a reasonably clever mind, and someone who devoted himself to treating her well. A clever girl should know how to choose. To Bai Su, the most important person in the world was her Bai Zhu. He was her friend and family, and perhaps, once she understood romance well enough, he might also become her husband. Unfortunately, before that could happen, she found a man who looked exactly like Bai Zhu... A man who wanted both to love her and to strangle her... P.S. The male lead only thinks about getting revenge on the female lead. In reality, all he can do is rage helplessly at her. He's a workaholic with an added wife-spoiling streak. The female lead's feelings for every male character other than the male lead are purely familial or platonic. At heart, this is a one-on-one romance, though there will be a few love-triangle-style scenes along the way. Theme: Everyone is a one-of-a-kind diamond.
