Synopsis:
"You're the fake young master in a switched-at-birth story. You enjoy the real young master's family, friends, parents, and education. You're greedy and want it all. When the real young master comes home, you try to kill him. In the original story, the real young master fakes his death and cuts ties. Everyone gradually sees your true colors and regrets what they've done, but by then the real young master no longer needs your insincere affection."
"The real young master finds people who truly love and cherish him."
"As the fake young master, you'll meet a very, very, very miserable end: disability, cancer, begging, car accidents, prison, ending up in the red-light district, and so on. That's the price you pay for hurting the real young master and stealing his life. But you aren't that kind of person..."
"You've received a higher education. You've seen mountains, rivers, and seas, and read works of great beauty. You've lived in luxury, and you've worked hard from the bottom up. The plot wants you to turn against each other, with jealousy and resentment filling every moment of your future life. Now the choice is yours. As the fake young master, will you follow the path of the original story?"
The fake young masters: "Obviously not! I'm not an idiot, a moron, or someone with something wrong in the head!"
"Host has awakened. Please treat the real young master kindly. Stop NPCs from being influenced by the plot and hurting him. Help clear the obstacles in the way of his happiness. After completing your mission, you will escape the original story's tragic ending and live a long life free of illness and worry."
As for the real young master, the fake young master dotes on him, protects him, cares for him, and loves him. The two of them lie naked together in bed, panting, and only then does the System realize something has gone horribly wrong. At what point did things go off the rails between the real young master and the fake young master?!
