Go Away! You're Not the One I Want to Pursue [Book Transmigration]

(The title and blurb are not final and will be revised before the story begins.) In short, the protagonist originally intended to transmigrate into a book and win over the male supporting character, but through a twist of fate, ended up with the male lead instead. This is a transmigration-into-a-book story with elements of the Fourth Calamity. The protagonist joins a holographic game about transmigrating into a book to win over the male supporting character. One hundred contestants enter the book-world instances, where the System assigns them random identities. The winning condition is to reach 100 favorability with the male supporting character. Male supporting character: Don't come any closer! In the end, through a twist of fate, the protagonist gets the male supporting character together with the original female lead. The male lead is the original male lead of the book's world, who has gained self-awareness. One day, he discovers: He actually has ten biological younger sisters, and they all seem to like his nemesis; His office actually has ten secretaries, and they all seem to like his nemesis too; His family's longtime friends are caught up in a dispute over the identities of their real and fake heiresses. Ten real heiresses and ten fake heiresses are causing trouble like crazy, and all of them are deliberately or otherwise getting close to his nemesis. Male lead: Am I losing my mind, or is this world going crazy... That's more or less the basic premise. I haven't figured out the rest yet. All in all, it's a goofy game story. The players who enter the game are basically just there to mess around, not to get emotionally invested. * Idea noted down on September 19, 2021, with proof of authorship. Theme: Love life
