No CP + System + Satisfying Revenge + Transmigrate into a Book
The plot isn't very logical, so feel free to read without using your brain.
A burned-out office worker had so many grievances after reading novels that she transmigrated one day. To get back to reality, she began a journey through different worlds.
One: I became an invisible cannon-fodder character in an old-school angsty romance.
Two: The invisible sidekick of a fake heiress.
Three: I actually became the mistress brought back from the borderlands...
