“Primum non nocere.”

A sweet yet difficult journey to get his ex-wife back.

She had a marriage contract with him. Her father forced him to marry her because she loved him so deeply. However, he didn’t love her and asked her to sign an agreement, according to which they should split the cost of living, have no children and get divorce four year later. She accepted all conditions because she thought that she was able to melt his heart.

However, after three years, nothing changed. He was still as cold as ice. At that time, another woman appeared. She was his co-worker, and she called him “Brother Chen”. Lu Yao gradually discovered that their relationship seemed to be vague.

What was worse, she was unexpectedly pregnant, and she wanted to give birth to their children. As she believed that he would definitely make her have an abortion, she told him that she was going to divorce him.

To her surprise, he refused to leave her and started to treat her with passion like he never did before. He hounded her nearly every day. It seemed that he realized the importance of her only after he was about to lose her.

And he found that she was so charming when she no longer pleased him and started to live her own life.
