The Reason Why the Heroine Doesn't Have a Flag

For reasons unknown to her, she and he were reincarnated into the world of an otome game. She became a villainess who would knock down the heroine, and he became a target for the heroine to conquer. The two of them were supposed to eventually take on such roles, but because they both retained memories of their past life, the story did not proceed as the game intended. The reason why flags are not being set up for the heroine begins from their childhood.
