[Preview Blurb] Si Jiaheng transmigrates into a rebirth novel, not as the protagonist but as the child who was switched at birth with the heir of a powerful family many years ago. The rightful heir, Lu Yinzhe, was bullied from childhood by the arrogant and cruel original Si Jiaheng, and his personality became twisted. As an adult, he grew gloomy and ruthless. The reborn protagonist knows what happened in the past, and schemes to make the powerful family find their true heir, becoming the only light in Lu Yinzhe's heart. The original Si Jiaheng falls from his lofty position, is tormented by the two protagonists until he can't recover, and becomes one of the cannon fodder characters. Fortunately, when Si Jiaheng arrives, Lu Yinzhe is still young, and their relationship hasn't reached a hopeless point. He thinks: Once I repair my relationship with Lu Yinzhe, I'll just wait for the reborn protagonist to come and take him away. Then they'll get on with their romance, I'll live my own happy life, and everything will be perfect. Who could have guessed that when the protagonist confesses to Lu Yinzhe, Lu Yinzhe smiles faintly and says, "I'm sorry, but I belong to Jiaheng. He won't let me have any other kind of relationship with you." Si Jiaheng: "...What did you say?"
