Jiang Shi'an has a secret: she is the Fifth Prince of Da Ling, but beneath her robes, she is a woman. She is secretly in love with someone: Zhao Wanqiu, the Third Miss of the Minister of Revenue's household!
Her twin brother, Song Shikuan, is going to ask their father for permission to marry Zhao Wanqiu. Jiang Shi'an is insanely jealous!!! But all she can do is drown her sorrows in wine.
After one drunken night, an imperial edict arrives.
That lofty father of hers has actually arranged a marriage between her and Zhao Wanqiu!!!
Jiang Shi'an feels as though the sky above her has split in two: on one side, the sun shines brightly and the breeze is gentle; on the other, lightning flashes and rain pours down!
Zhao Wanqiu had originally set her sights on Jiang Shikuan, but the imperial edict marries her to Jiang Shi'an instead. She calmly puts on her wedding dress, spends their wedding night alone in an empty room, and pays no heed to the servants' gossip.
What puzzles her is that during the day, Jiang Shi'an fusses over her with the devotion of a lovesick fool, but at night, she stammers and avoids her as if she were a tiger. Still, whether Jiang Shi'an's feelings for her are genuine or not, Zhao Wanqiu has never believed she would give her heart to someone so timid and good-for-nothing.
So why does she find it so irritating to see the Princess of Daze coming out of Jiang Shi'an's study!
Note: At first, the disfavored prince pretends to be incompetent, and everyone knows she is a good-for-nothing at both literature and martial arts.
Later, she drops the act, reveals her true strength, and takes on her father and the court head-on, rising to rule the world as a woman!
Bonus scene:
"Your Highness, do I have any faults in my conduct?"
"No."
"Am I too ugly to please Your Highness?"
"Not at all."
"Oh~ So Your Highness has someone else in your heart, someone you love?"
"No!!! Absolutely not!!!"
"Then... does Your Highness have a hidden ailment???"
At her words, Jiang Shi'an's handsome face turned a deep purplish red. She seemed unwilling to accept it and wanted to speak, but stopped herself...
"Your Highness, forgive me for disturbing you." Zhao Wanqiu quietly left, remembering to gently close the door behind her.
…Jiang Shi'an clenched her fists, her whole body taut. After a long while, a sigh filled the entire study... She had the desire, but not the ability... That must be the ailment...
Happy ending, so enjoy without worry.
