Transported into ancient times as an abandoned wife forced to leave her marital home with nothing, Lin Wan immediately turns the tables by pulling out her dowry inventory and demanding an accounting. Want to take my dowry? Let's settle the accounts first. She opens a Marital Separation Office, offering legal assistance to noblewomen seeking marital separation. One by one, a Grand Princess, a lady of the Shen family, a military general's widow, and a merchant's legitimate wife come knocking. She meticulously sorts out their accounts, puts reason first, and lets the law follow. Shen Yan, an official in the Ministry of Justice, goes from investigating her to helping her. As they take on one case after another, the two become increasingly in sync. Even when it comes to marriage, Lin Wan insists on settling the accounts before giving her answer. An ancient-era family lawyer starts with a single teahouse and ends up with a chain of offices. When the accounts are settled, people can walk away freely. The more you watch, the more satisfying it gets.
