Xiao Xuan, who was cursed and trapped in the whirlpool of power, had been alone and disguised since he was a child, struggling in the intrigues of the court, thinking that he would be swallowed by the curse or be shattered on the road to seizing power. Until the appearance of Su Qingyue, a traveler from another world, broke all his predictions.
Carrying notes full of strange symbols and unknown knowledge, Su Qingyue fought for her life and saved Xiao Xuan twice, using her calmness and wisdom to find hope for him in desperate situations. The "cost calculation" she talks about is the ultimate cherishment of life; every time she uses her abilities, it is at the expense of overdrafting herself.
Xiao Xuan once regarded her as a chess piece, but after seeing her fragility and loneliness, he fell completely. He took off his armor, used his heart as a shield, and vowed to protect her and bear all the costs for her. The disputes in the palace have not ended, the prince's conspiracy is still there, the shadow of the curse has never dissipated, and this pair of souls across different worlds have become each other's light and salvation in the darkness.
A game about power, curses and affection has since begun. They are dependent on each other and go through ups and downs in other worlds together.
