I, Rikko Kujouin, am a poor girl with no family. My grandmother, who passed away two months ago, was a spoiled lady with no survival skills. My father, who left me as an infant, ruined the Kujouin family and is still missing. I was raised by Fuki, my grandmother's maid. Thanks to Fuki, I learned how to survive. On the other hand, my grandmother, who had studied piano in Europe, tried to educate me as a proper lady of the Kujouin family, teaching me piano, dance, manners, and languages. Despite this, I became a scholarship student at the prestigious Meisei Academy. On the day of the entrance ceremony, I was tackled from behind and called an 'Antagonist Lady' by Yuria Sakurada. She seems to believe that this world is a dating game. She warns her childhood friends (whom she calls 'target characters') to be wary of me and tries to pair the heroine, Miharu Yuki, with the target character, Ryo Torigoe. I am too poor to care about such things. However, it turns out that Fuki was taken in by Ryo Torigoe's family, and she is his great-grandmother. He scolds me for mistreating Fuki, but I want to see her again. Then, my house is destroyed by a landslide. I must be strong and not give up!
