What was the name of the story of two people meeting again after being reborn?

After the female protagonist of " Seeking the Title of the Book " died, the King of Hell made him reincarnate into his previous life. Actually, it wasn't his previous life. The male protagonist was a prince or something. Later on, his boyfriend also came. In order to find him, he came up with a modern riddle to let people guess. He seemed to have seen his boyfriend sleeping with another woman and fell down the stairs to his death? The one in ancient times was killed by the concubine of the prince. It might be a bit messy, but that's all I remember.

Answer 1

The one I recommend to you is <<The Reborn Concubine's Daughter>. The female lead of this ancient romance novel was reborn with hatred. Lin Yingxue swore to change her fate! The man she loved the most in her previous life bullied her, humiliated her, and even conspired with a mistress to kill her. In this life, she wanted to get back all her debts! She fought against the royal family, controlled the court, beat up the scumbags and sluts of her previous life, and even shamelessly asked for cooperation from a beautiful prince. The male lead was this prince. He gently pressed her hand down."Tang 'er, the golden thread cut your hand. Put it down." Gu Xitang immediately switched to complaining mode."They bullied me first!" The man smiled faintly and opened his thin lips."I'll take care of these things that are in your way." Later on, the world knew that the virtuous king who was untainted by dust was the King of Hell when he tore off his white clothes. And the King of Hell had appeared only for Gu Xitang. I hope you like this fairy's recommendation. Muah ~😗
