[One-on-one romance + both leads are each other's first and only + marriage first, love later + powerful man learns to bow his head + mature leads + both leads transmigrate five years into the future]

Shen Tang is a young lady who has come to seek refuge with the Duke Zhenguo's household. After plenty of twists and turns, she finally wins the favor of the second branch's legitimate son. But on the eve of their wedding, an accident sends her and the household's cold-faced young lord five years into the future.

The good news is that she got what she wanted and married into a prestigious family.

The bad news is that her husband five years later is her former fiance's elder brother, that otherworldly young lord. She never meant to climb quite that high!!!

Shen Tang is too stunned to speak. The aloof, proud young lord has actually fallen for her!

And most importantly, they even have a son together?

Overnight, she becomes a mother without having to give birth!

As the Duke's eldest legitimate son, Xie Xiao shoulders the burden of bringing honor to his family. In his more than twenty years, he'd never once considered marrying or having children. But an accident sends him five years into the future, where he discovers he's married to his younger brother's fiancee.

He remembers her as a woman with snow-white skin and stunning looks, who used underhanded tactics to get engaged to his second brother.

How could he have done something so shameless and immoral as taking his younger brother's betrothed?

A crack appears in his perpetually icy expression. But then a child's voice calls him "Father," making his pupils contract.

This is bad!

Really bad. He's gone and made a baby with her before they were married, and now they even have a child.

P.S.:

Five years later, the female lead is 21 and the male lead is 27.
