Transmigrated as a Good-for-Nothing Male Supporting Character (Another World)

A special warning: This story has bizarre logic and questionable morals. If you can't stand it, please graciously click X. What are male supporting characters for? To make the male lead look good, to be cannon fodder, and to deserve all the mockery. One day, Yu Chen gleefully mocked a novel, saying, "That male supporting character is such a loser. Anyone could kill him so easily." Then he transmigrated... ←_← [Wasn't that a little too convenient?] What? There's a mission? He has to follow the original plot, but he can't be killed by anyone other than the male lead. Otherwise, his original self will collapse too, and he won't even have the chance to return to reality. But one wrong step leads to another. Can someone tell him what the heck happened to the plot? Why isn't it following the original anymore? Why has the male lead turned evil? And why does he want to overpower me? [The male supporting character has somehow been redeemed without even realizing it. What the hell!] Male-male romance, top and bottom: ordinary, hardworking bottom who won't meekly accept his lot. [The male supporting character gets a three-headed dragon as a pet. If that's a deal-breaker, don't read.] The author appears to be a lunatic with bizarre logic [stares into the distance]. Feel free to jump in, everyone. Clarification: Is Sten's love for Yu Chen love at first sight? Answer: Nope. I know his affection seems strange when you read it, but I didn't write it without reason. They definitely had a tangled past. [Hey, hey.] Drafts of my new story are available.
