Xie Ai returns to her hometown for a holiday, but can't take any more of her elders pressuring her to get married, so she runs off early.
She never expects to have an accident on the way back. When she opens her eyes again, she's been transported to the 1970s and become an eighteen-year-old girl who was nearly bullied by her stepbrother and is now fleeing to the army to find the man promised to her in an arranged marriage.
But when she reaches the army, she's hit with the news that he's already married. His wife, Zhao Qiuhong, was originally set up on a blind date with one of his comrades.
Just as Xie Ai is preparing to find another way forward, a military district leader gets an idea and tries to match her with the unlucky man whose fiancée was stolen from him.
Xie Ai doesn't expect much, but the man is tall and straight-backed, handsome and steady, and at twenty-five he's about to become a regiment commander. She has no reason to refuse.
Zhao Qiuhong rushes over and tells her the man is cold-hearted and doomed to die young, advising her to turn him down.
Xie Ai declines the warning and sticks to her decision. She's not doing it out of spite. She knows they are living in a novel, and that one day the man will become a major figure whom the male lead greatly admires.
As for him being cold-hearted... Xie Ai rubs her aching waist and thinks indignantly that she wishes he were a little colder!
The night Zhao Qiuhong receives word that her husband, Zou Qianli, has died in the line of duty, she is reborn. This time around, she absolutely refuses to marry that dull, wooden man who cares only about work and is doomed to die young. So she arranges to marry his promising comrade instead.
A month later, Zou Qianli marries his former fiancée and moves in next door to her.
She tells herself not to pay attention, but every time she quarrels with her husband, she can't help standing by the wall to spy on what's happening next door.
What makes her even more frustrated is that Zou Qianli, that stern, stony man, gradually spoils his wife into a pampered young lady who never lifts a finger. He does all the housework, hands over his entire salary, won't let her touch cold water when it's chilly or go into the kitchen when it's hot, and even washes her underwear!
What breaks her most is that Zou Qianli's supposed death in the line of duty was a misunderstanding!
When she sees Zou Qianli standing perfectly well in the doorway, smiling at Xie Ai, Zhao Qiuhong is almost instantly overwhelmed with regret.
