FL was an orphan who her brother and sister-in-law want to sell for just 2 pigs. Thankfully, ML arrived just in time when she was being tied up to a cart. ML, just like the FL's father, was a soldier and he brought the body of FL, 's father to be buried.

Later on, she was saved from his evil bigbro and become the wife of ML. You see, if you've been reading ancient theme chinese novels, having a wife in ancient time can be done verbally. Specially in rural areas and ancient war times. Most of the time, certification are not needed and a simple ceremony can be done.

At first, ML thought that the baby was FL's child due to the evil bigbro's lies but later on, when FL learned how to write, she told him that it was her baby sister. Anyway, FL is mute due to fever when she was a child.

ML, due to his scholar background, knows that being a soldier in war time have a dark future ahead so he keeps delaying their 'first night' saying that he needs to make her healthy first or fatten her up.

Later, when ML and his fellow soldiers marched to war, an Aunt/neighbor told her that the courtyard they were living was given to her as a dowry in case he will never came back. FL implied that she will wait for him for life and just raised her lil sister.

After more than 7 months, ML returns and both have proper marriage and live happily together.
