Transmigrated Into A Ruined Novel As An Extra TRNE

Ren is a young university student living a lonely life on earth as a normal human, of course, until one random night where he goes to sleep and miraculously wakes up to a pool of blood, but wait... this isn't his house, and this body, it doesn't belong to him.

Unexpectedly, Ren finds out that this new world he is in is the same as the one from a novel he used to read, and he wasn't transmigrated as the hero who would 'save the world', get all the girls, and level up through the power of friendship and plot armor, no, he had become a character that was only mentioned in two chapters of the entire novel...

It seemed like a sure loss at first, since this novel had a tragic ending all because of the main character's decisions, but Ren really didn't want to die along with the world, so he would have to make efforts to make sure the story doesn't go down the original path.

"Since I'm not a weakling, I can affect the cause of the world actively and not just from the shadows... Heh, my dare MC, you might have to give your life for the cause."
