One Character Changed, and the Fake Young Master Became Everyone's Darling

After transmigrating into a book, Lou Muchen became a fake young master. The System gave him a golden finger that could change the plot, but only by changing a single character. Well, something is better than nothing. Lou Muchen gladly accepted.

But the System never said the golden finger would leak. As he kept changing things, his whole family heard his inner thoughts, and before long he became the family's favorite. Even the real young master's gaze toward him grew increasingly strange. Wait a minute, did I change romance into boys' love? Damn it!
