I Was Transported into a Fanfiction and Forced to Play the Background Character

Lin Che is an ordinary high school student. After staying up all night to finish a 300,000-word fanfic, he wakes up to find himself inside the book, as "Background Character A," who gets knocked flying by the protagonist on page three and doesn't even have a full name. Even more absurdly, the book is credited to him as its author. But he swears he never wrote it. The good news: he's read the original and knows the whole plot. The bad news: he only gets three lines in it, and "dies" right at the start. To make it to the ending, Lin Che teams up with "Glasses," Background Character B, who also won't survive past page three, and forms the "Background Characters' Mutual Aid Alliance." Their only goal: survive together without attracting the protagonist's attention. But he soon discovers that this world is far more complicated than he imagined:

· The final page of every setting guide has annotations in his handwriting: "Don't trust the System."

· The System's stated mission is crystal clear: "Maximize the Host's comedic effect without killing the Host."

· A transmigrator who calls themself an "original-story fan" is hunting him down, on the grounds that "Why should a background character like you get to change the plot?"

· And that line of chalk on the rooftop floor, "Background Character A died here," doesn't look like a joke at all.
