Akuyaku Reijou, Cecilia Sylvie wa Shinitakunai no de Dansou suru koto ni shita

I reincarnated as the villainess in an otome game. If it proceeds like the game, what awaits me is either a 'death in anguish' or an 'instant death'. I'll die on any route. At this rate, I'm going to die. If that's the case, I will change my fate! Therefore, I will become a man. But the story takes an unexpected turn when I made a mistake during an event…!! If revealed as a woman = instant death!! I will aim for a peaceful life!!
