After the Top-Level Detective Transmigrated into a Sickly Fake Young Master

Ruan Jiyu is the third young master of the Ruan family. Born weak, he is a sickly beauty, pampered since childhood, and known for his madness and mischief. At twenty-two, his father remarried, and it was discovered that they had been raising the wrong child. The youngest son, who had been spoiled for years, was actually not the true young master.

The real third young master is named Li Feng, a young celebrity with sweet dimples and a rosy complexion, the complete opposite of the cold and irritable sickly Ruan Jiyu. Coincidentally, he looks very similar to Ruan Jiyu.

Ruan's father renamed him "Ruan Jifeng," in contrast to "Ruan Jiyu." The fake young master Jiyu, due to a marriage contract, was "married off" by his father to the entertainment big shot, Lei Ting, due to a marriage contract.

In this life, because of the word "fake," he was treated as a substitute, tortured, and died unloved.

The ace detective of the Interstellar Peace Organization, code-named "Jiyu," failed a mission and jumped into the sea. When he woke up, he found himself in a novel about a wealthy family's struggle, as the fake young master and a sickly child.
