Lucinda, an orphan, is adopted into the House of Earl Lancaster as a substitute for their late daughter.

Days of cold treatment from her family continue, but on her 10th birthday, Lucinda regains her memories of a past life and decides to become a magician in this life, planning to travel someday.

Though she diligently studied magic every day, at the magic academy she entered at age 15, a beautiful girl claiming to be the heroine reveals a shocking truth to her.

"Huh, this is the world of an otome game, and I'm the villainess?!"

…But, since there seems to be no immediate threat of death, I'll ignore romance with the capture targets (my stepbrother, the prince, my homeroom teacher, and the prime minister's son) and diligently focus on my academy life!

For some reason, everyone tries to get involved with her, but Lucinda single-mindedly pursues the path of a magician—!
