It Was Only Physical Attraction, So How Did Mr. Lu Fall So Hard?

Yan Shuyi and Lu Huai have been married for three years through an arranged alliance.

They are passionate and intimate in bed, but talk only business outside it, making them the most compatible partners.

When Lu Huai's first love returns to the country and Yan Shuyi unexpectedly discovers she is pregnant, their seemingly unshakable marriage alliance becomes precarious.

Raised from childhood to be a strict, disciplined heir to a wealthy family, Yan Shuyi weighs the pros and cons before making her decision.

She will hide her pregnancy and make way for Lu Huai's love, in exchange for a long-lasting partnership between the Yan and Lu families.

To avoid becoming the discarded wife of a wealthy family in the eyes of the public and bringing shame on the Yan family, she secretly searches for a suitable man to marry into her family.

She even plans to find a new father for the child in her womb.

But the coldest and most levelheaded young master of the Lu family suddenly loses control.

When she sprains her ankle, he carries her and massages it. When she hits someone, he hands her a weapon and cleans up afterward.

When the Yan family mistreats her, he throws money and resources at the problem.

He even decisively deals with his first love when she comes to confront Yan Shuyi.

The more Yan Shuyi thinks about it, the more dangerous it seems. With her pregnant belly, she kicks him out of bed.

"Mr. Lu, we're only married for the sake of an alliance. You're crossing the line!"
