Chi Xuan wakes up inside a melodramatic novel titled *Universal God-Tier Darling*, where he has become the useless Crown Princess despised by the entire empire, a minor character doomed to a miserable end.
Chi Xuan, the cold-blooded, merciless, top assassin in his previous life: I'm done with this. Let the whole world be destroyed!
But the System tells him: If you don't complete your mission, you'll die, and you won't get to see the person you like.
Chi Xuan instantly changes his tune: All right, I'll do whatever you say. (Obedient jap)
But why is the plot getting stranger and stranger even though I've completed every mission?
The Imperial Crown Prince, who originally loathed him to the utmost: Remember your status as Crown Princess. If you dare seduce another man again, I'll lock you up and never let you go anywhere!
The sinister, scheming richest man in the empire: I want to offer every jewel in the universe to Xuanxuan. Won't you be my one and only collectible?
The iron-willed, domineering Imperial Marshal: I don't want to see traces left by other men on your body ever again. You were meant to belong to me alone.
The cold-blooded assassin x the bewildered Chi Xuan, driven to despair: How did things turn out like this? Where's the protagonist? Go after him, you guys!
Many liberties have been taken with the setting. There is a second gender (Chi Xuan will undergo differentiation), and same-sex couples can marry.
