A Strong Lady After Reincarnation, A Bellicose Lady Got Reincarnated!?: Its an Impossibly Hard Game Where I Would Die If I Dont Fall in Love, 転生したら武闘派令嬢!?～恋しなきゃ死んじゃうなんて無理ゲーです

Is this really the premise of your life? If you don't romance one of the yanderes, will you die? Before my previous existence, I was a notorious delinquent known as the "Crimson Rose" or the "Crimson Demon," who had gained popularity among other delinquents. My skills in romantic relationships were non-existent since talking with fists was easier than discussing love. However, it appears that you have reincarnated into a game heroine, someone from a respectable family and with a gentle demeanor. To ensure your survival while working together on the investigation, you will make an effort to fall in love, but...the person herself is unaware of this situation. This story follows Serina, the daughter of an Earl and a former delinquent, as she searches for happiness.
