Synopsis

In an accident during her "oshi activities," the protagonist is reborn as the duke's daughter, Elicia. However, because of her black hair and black eyes, she spends her days being scorned as the "Daughter of Evil." One day, she meets Crown Prince Reichelt and discovers her "oshi" for this life. She's actually a saint, but as long as she can continue her oshi activities without being found out, there's no problem!? Too focused on her oshi activities, she doesn't realize the overwhelming love coming from her oshi!? A sweet, slightly misaligned love story! (Source: Kadokawa, translated)
