A poor-born heroine investigates her older brother's wrongful conviction by disguising herself as a man and taking the place of a nobleman's son to sit the imperial exams, only to fall in love with the mirror-image personality of the person she's impersonating. It turns out the real noble young master was cursed by his family, splitting his soul into two halves: Day (a gentle, refined scholar) and Night (a violent general). She must make both personalities fall in love with her to reunite the soul and uncover the truth.
