"I was sold off to a cold-hearted moneylender to pay off debts," but my husband was so impressed by my "money-saving skills" that he entrusted me with all household finances, and now every day is in the black and I'm happy.

A destitute young lady, Emma, who was oppressed by her extravagant family and forced to marry "William," a ruthless moneylender, to repay her family's debts. However, his mansion was a money pit full of wasteful spending! "What a waste! I could produce twice the satisfaction with half the budget!" As she rebuilds the finances with her ingrained frugal nature (money-saving skills), William inexplicably becomes deeply devoted to her...? "You are the perfect partner. I will never let you go." A newlywed life filled with happiness and black ink—starting from careful accounting.
