Amy was an ordinary college student, independent and rational, dreaming of quietly finishing her degree, landing a stable job, and living a "no-romance-brain" wonderful life. One day, she accidentally opened an ancient book in the library and accidentally summoned two incubi—the aloof, ascetic Incubus Prince Damian and the sunny, goofy Incubus Knight Lucien. The two had been sealed in the same book due to a "succession dispute" in their realm, and now had to complete the trial of "making the same human fall in love with them" to return and compete for the throne. The problem was, Amy had zero interest in this "Mary Sue romance" and just wanted a normal life. Her goal became: find a way to send these two troublemakers back and restore her normal life. Otherwise, the two incubi would keep pestering her and wrecking her life plans. Worse, Damian and Lucien, competing for Amy's affection, launched an absurd "seduction contest" across campus, leading the whole school to think Amy was a "two-timing gold-digger."
