The entire Shen family “perished in a sea of flames,” and the one who wielded the blade was Xie Jin, the powerful commander of the Imperial Guard.
Shen Zhiwei, the sole survivor, changes her appearance beyond recognition and disguises herself as a lowly maid called “A Chou.” She infiltrates the Lu residence, vowing to kill her enemy with her own hands.
Xie Jin calmly arranges for her to serve by his side. Life in the residence is full of strange twists: he smiles and drinks the soup she clumsily brings him, and when she “accidentally” spills scalding tea, he reaches out to catch it with his bare hands. He indulges every clumsy “trick” she tries…
During an assassination attempt, he is gravely wounded protecting her. With trembling hands, she saves him, tears falling silently. “Xie Jin… I’ll repay you with this life!” One rainy night, her disguise falls away.
He touches the red birthmark behind her ear, revealed by chance, his breath burning as he softly speaks the name he has kept buried in his heart: “My benefactor… I’ve finally found you.”
