Suzuki Nanako, the pampered third daughter of the Suzuki family.
Beautiful and delicate, with a captivating charm. The Suzuki family, whose members from the oldest to the youngest all adore beauty, have treasured her since birth, fearing she'd be hurt if they held her too tightly and melt away if they kept her in their mouths.
Alas, beauty is short-lived. Ever since she was born, the Third Miss Suzuki has been frail and sickly, suffering from one illness after another, both major and minor, even in the fabulously wealthy Suzuki family. This only made the family dote on her all the more.
But only Nanako knew that her body merely looked frail. In truth, there was nothing seriously wrong with her. She had explained this to her family many times, but somehow no one believed her.
Suzuki Sonoko stared at her little sister coughing up blood and screamed, "Doctor!!! Nana's coughing up blood again!!!!!"
With blood at her lips, Nanako wore a distinctly exasperated expression on her delicate, fair face for the first time. It wasn't because her sister once again refused to believe she was fine. It was because, at some point, she had found herself surrounded by her former "lovers"...
Content warnings: Harem-style, adored-by-everyone Mary Sue; the heroine is physically frail but the strongest fighter; OOC; characters and timeline all serve the plot.
Premise: I'm proud to be human
