He thinks he has finally been handed the protagonist's script and can make a name for himself, but before he even gets started, he discovers that every member of his family is a bizarre character! Eldest brother: Usually keeps a low profile, spending every day shut away in the library and never going out, yet somehow knows everything happening in the world. His gaze is as deep as an abyss, mysterious and impossible to read! Second brother: Once renowned throughout the region as the Ye family's prodigy, he unexpectedly became a cripple and had his engagement annulled by his fiancée's family! Father: A true schemer, devious to the extreme. Little sister: A peerless little enchantress, bewitching in every gesture... And that's not all. The old steward answers every call, the guards have connections on both sides of the law, and the wife he married casually refers to herself as "I, the Emperor"!
