[Alternate world + misunderstandings + palace intrigue]
The General Who Guards the North is gravely wounded and falls off a cliff, only to be rescued by a reclusive female physician.
He doesn't know she's the legitimate daughter of the Marquis's household, who supposedly “died of illness” five years ago. She doesn't know he's the son of the enemy who wiped out her family.
Three months of recuperation in a bamboo cottage, and feelings begin to blossom.
Then she spots a military token at his waist, engraved with the character Pei. It bears the mark of the rebels who massacred the Marquis's household.
That night, she leaves a note saying, “May we never meet again,” and disappears without a trace.
Five years later, during a plague in Jiangnan, he is sent to provide relief and encounters a renowned physician distributing medicine.
The moment he tears open her sleeve, he sees a scar on her wrist, identical to the one borne by the physician who tested medicines back then.
“General, please mind your manners.” She pulls her hand away with a faint smile. “I am already promised to the Crown Prince.”
His eyes bloodshot, he tears off his armor. “I'll trade all my military honors for the chance to tell you the truth...”
“The one you are to marry today is the person who impersonated the Pei family army back then.”
