Duke's daughter Alinne has a cold, distant relationship with her fiancé, Crown Prince Clovis. One day, she sees a certain girl and suddenly realizes: "I used to be an ordinary office lady!" This is the world of an otome game. The girl she saw is the heroine—her absolute favorite from her past life. And Alinne herself is the villainess destined to be cast aside. Her plan is simple: support the heroine and prince's romance while happily watching her "oshi" from the sidelines. But to her shock, Clovis starts getting closer to her, speaking sweet words that confuse her heart.
