[Marriage first, love later + period setting + family life + accompanying the troops]
When Cheng Shuning opened her eyes, she found herself caught in the middle of a "caught-in-the-act" scene. And wouldn't you know it, she was the one at the center of it, while the male lead was her cousin's fiance?
She wanted to scream at the heavens. What kind of disastrous start was this?
To honor a promise he'd made to a comrade, Wei Muyan married his comrade's younger sister. He traveled a thousand miles to Fengning City, only to be set up on his very first night at the Cheng household and end up in bed with his comrade's younger female cousin.
With things having come this far, Wei Muyan could only grit his teeth and accept it. He had no expectations of love or marriage anyway, so it made no difference whom he married.
Later, Cheng Shuning couldn't take having this man demand her every night anymore. With her belly swollen, she put her hands on her hips. "Wei Muyan, I want a divorce!"
Wei Muyan, now a high-ranking official, shed his usual icy demeanor. Wearing a pleading expression, he followed his wife and coaxed her in a meek voice.
"Honey, don't be mad. Can't I just admit I was wrong?"
Wei Muyan at first: What's so great about having a wife? Building a career is much better!
Wei Muyan later: Mm, but my wife is better!
This is all about him getting his comeuppance.
