You are the heroine of a popular-girl manga.
Everyone fawns over you and tries to please you, hoping to win your favor.
But your ending is a lonely old age, spent as a shut-in with video games and novels for company.
Readers who liked you and had invested in their favorite romantic pairings were furious at this ending. Their resentment was so great that it caught the attention of the world's consciousness.
"I hope OO-chan finds a beautiful love."
"Don't make the romance too forced."
"The other person should be excellent and positive."
And so you were bundled off to a crossover world of sports anime.
But clearly, anyone capable of ending up alone wasn't ordinary. Even after childhood friends and classmates turned out to be a whole sea of handsome, exceptional guys, you remained unmoved. So the world's consciousness assigned you a System.
It was a romance-assistance System that claimed to be a background-character plot System.
It told you, "With multiple worlds merging, we're short on bit characters. We urgently need a batch of background-character temp workers. That's right, you! You, the background girl, have been selected!"
You stared at the infinitely long task list in your hands, speechless.
Shady System: "Daily pay, 50,000 yen an hour. There are employee benefits, too, like rare doujinshi and limited-edition cartridges provided through the proper channels."
You: "Please, let me become the best little workhorse!"
And so you started playing out plotlines on one set after another...
