In a previous life, the protagonist reincarnated as the villainess of an otome game, having previously been a male. However, he needed to learn the game’s content. On the other hand, the game’s heroine was well-acquainted with the game and was also a reincarnator. Neither of them knew that the other had reincarnated. The protagonist only knew the heroine from the game and wanted to befriend her. However, the heroine didn’t just want to be friends with the villainess; she wanted to possess her. When she sneaked into the young villainess’s house to secretly take photos, she was caught by her older brother and had her camera confiscated. But she didn’t give up and continued to peep every day. The villainess’s brother was a target for conquest in the game, so the heroine tried to use him to get closer to the villainess. The heroine was willing to do anything: secret photography, wiretapping, stalking. When they reached middle school, the heroine began to eliminate those who would be the cause of the villainess’s downfall, getting them expelled or even sent to prison. However, the heroine miscalculated. The supposed-to-be-hated villainess was well-liked within the school. The heroine decided to make the villainess hers forcefully. The villainess herself was completely unaware of this.
