Kenkyo, Kenjitsu o Motto ni Ikite Orimasu Novel

A protagonist discovers she has been reincarnated as a villainess in a shoujo manga she once loved reading, "You Are My Dolce." She has become Kisshouin Reika, a wealthy antagonist who bullies the commoner heroine and interferes with her romance with a rich boy called the Emperor. According to the original story, Reika was meant to face the Emperor's revenge, leading to her family's ruin, while the protagonist and Emperor eventually became a happy couple. Unwilling to accept this tragic fate, the newly reincarnated Reika decides to alter her path. Rather than play her role as the villain, she plans to quietly erase her presence to avoid angering the Emperor and ensure her family's survival. This strategy, however, creates an unexpected problem: without a villain to oppose, the original story cannot progress as written. Meanwhile, Reika focuses on studying and saving money to secure a stable future after what would have been her family's downfall.
