His One and Only Minister

The day she announces her engagement, he suffers a heart attack and is admitted to the hospital.

Nan Chu lived with the Zhou family for six years, secretly loved Zhou Huaiyan for three, slept with him, and got pregnant.

But Zhou Huaiyan was busy going on blind dates and arranging a marriage alliance. He treated her with disdain, as if she were worthless.

By the time Zhou Huaiyan falls in love with Nan Chu, she has already left the Zhou family and become a renowned top agent in the entertainment industry. She also has a devoted man who belongs to her alone.

A review of the three men, in order of appearance:

Zhou Huaiyan: The more of a jerk he is at first, the more deeply he falls for her later. He doesn't realize that, to Nan Chu, affection that comes too late is worth less than grass.

Shen Yi: For Nan Chu, he gives up the job he loves to enter a line of work he hates, cutting through every obstacle and shielding her from the storm.

Zhou Jinnian: He may let down the whole world, but he would never let down Nan Chu.

[This novel has only one female lead. Whichever man she chooses in the end is the male lead.]
