- Description from novelbuddy

Su Jianan was marrying the love of her life. It all seemed picture-perfect, except for a few catches. One, it was a marriage of convenience. Two, she would be divorced after two years.

In 2076, technology did not bring a better life to people, but instead became a tool used by the rulers to exploit.Arthur traveled to such a cyberpunk world and accidentally obtained the check-in system.You can get a variety of technological knowledge just by signing in.Before he could do anything, he unexpectedly discovered that the original owner was already married and even had an older son.Arthur: “The freedom of marriage is sacred and inviolable. That's not my wife.”Why are you saying that my wife is Gloria and I have an older son named David?Arthur: “How can a human being abandon his family and his son? Just go with peace of mind as the original owner. After your death, your wife will be taken care of by me, so don't worry about it.”

When a terminally ill young man awakens in the world of his favorite childhood game, he realizes he isn’t the protagonist, the destined hero, or even a major side character. Instead, he has become an extra—a disowned noble barely clinging to relevance in a world where strength determines everything. Worse, his fate in the game was to die an early, meaningless death.Armed with only his knowledge of the game’s storyline and a common system that tracks his stats and skills, he is determined to survive. But mere survival isn’t enough. He remembers a hidden easter egg from a long-forgotten anime collaboration: the Mangekyō Sharingan—a power limited by game mechanics but unrestricted in reality.With Kamui as his trump card, he walks the fine line between fate and freedom, seizing power from the shadows while avoiding suspicion. As the protagonist and his allies battle against demons and unravel the game’s grand destiny, he secretly builds his own strength—manipulating events, mastering forgotten arts, and even forging ties with villainous factions.Will he remain a footnote in history, or will he carve his own legend in a world that was never meant to be his?
