The late emperor entrusted his orphaned heir to his ministers and laid out a grand scheme of checks and balances. An imperial edict of marriage ordered Su Sijin, the Grand Tutor's legitimate daughter, to wed the regent, Chu Junheng. The marriage was presented as an alliance, but was really meant to keep watch over him, using a loyal minister's daughter to restrain a powerful official.
Everyone believed Su Sijin was gentle and compliant, unaware that she had grand ambitions. This marriage was precisely her stepping stone into the heart of power.
A sudden thunderclap struck, and the two unexpectedly switched souls. The God of War found himself confined to a woman's quarters, experiencing firsthand the restrictions women endured, while Su Sijin took command of the regent's body and entered the court.
On a stormy night, their souls returned to their proper bodies, but hearts had already changed. Chu Junheng deeply loved Su Sijin, understood her ambitions, and was willing to wield his spear and clear a path for her. Su Sijin was moved, yet remained clear-eyed: her ambitions for the realm mattered more than love. The two broke free of the late emperor's game, joined forces to unravel the situation, and vied for control of the realm.
