Chaehee, the cherished youngest daughter of the Minister of Rites, has led a sheltered, aristocratic life. Yet lately, her eyes keep wandering toward the family's new hired hand, Seok. She can't stop staring at his bursting thights beneath his pants, his bulging forearms flexing with every swing of the axe, and the defined abs exposed whenever his tunic slips up. ‘I am going to bed that man no matter what.’ Completely smitten, Chaehee plots to seduce him at every turn, only to be rejected time and again. However, the balance of power shifts when Seok approaches her with a surprising proposition. To settle a debt for Yunhyeong, Seok offers his own body as payment to the young mistress. "A lowly servant is paying his dues, so you had better receive it well, Lady Chaehee." "Haah… ah!" "Since you love it so much, I'll have to pay you back constantly. Day or night, just say the word and I'll plow you thoroughly." Bound by the agreement, Chaehee finally gets her long-awaited wish, submitting to Seok's relentless physical service.
