She's a sickly villainess, but her fiancée is so overprotective that she wants to run awayByoujaku na Akuyaku Reijou desu ga, Kon'yakusha ga Kahogo Sugite Nigedashitai (Watashi-tachi Kenen no Naka deshita yo ne!?); 病弱な悪役令嬢ですが、婚約者が過保護すぎて逃げ出したい（私たち犬猿の仲でしたよね！？）; She's a Sickly Villainess, but Her Fiancée is So Overprotective That She Wants to Run Away; The Fight and Flight of the Sickly Villainess

A corporate slave in her previous life, our protagonist finds herself reincarnated as Fiona, the villainous noble lady in an otome game she used to play. Finally, this is her chance at a leisurely life... but it turns out that Fiona is actually quite sickly and weak. Hey, this was not in the original setting!! But now, everything makes much more sense. Clearly Fiona was a villainess in the original game because she was always unwell and ended up taking her frustrations out on others... If things continue like this, Fiona won't be able to live a leisurely, slow life! In order to improve her health, she changes her lifestyle and attitude, but as soon as her fianc Louis, who had always been hostile to her, finds out about her situation, he becomes super overprotective. Why does he have to start doting on Fiona now?! "Breaking off the engagement? There's no way I'd do that." "From now on, you can ask me for anything. I'll make it happen. whatever it is." It's too sweet compared to the original...!
