[Military Marriage + Marriage First, Love Later + Switched Brides + Sister Contrast + Research in the Later Stages + 1970s]
In her previous life, Shen Nianqing was recognized as a genius in physics. She never expected her most trusted husband, Zhou Muci, to stab her in the back, accusing her of stealing his experimental data and turning around to claim she had committed academic fraud.
Her reputation ruined, she went home to confront him, only to catch him in bed with her stepsister.
She was forced to divorce him, left with nothing and thrown out of the house.
Her stepsister then gloated in front of her. Unable to take it, Shen Nianqing fought with her, and they both fell down the stairs and died!
When she opened her eyes again, it was the summer of 1979, one week before her wedding.
To her surprise, her stepsister, Shen Nianyao, had also been reborn.
In her previous life, she married the cold-faced officer Huo Beixiao, only for him to return from a mission with both legs disabled, a useless cripple.
Unable to endure the loneliness, she cheated on him and was thrown out by the Huo family.
Seeing Shen Nianqing living in glory, she grew jealous and seduced Zhou Muci.
After being reborn, Shen Nianyao schemed her way into Zhou Muci's bed.
Shen Nianqing decided to play along. She wanted to see how Zhou Muci would become a leading figure in physics without her research.
Shen Nianyao got her wish and married Zhou Muci, while Shen Nianqing became the substitute bride of the cold-faced officer Huo Beixiao.
Everyone laughed at her, saying she'd be a widow in all but name.
Who could have guessed that after the switch, the cold-faced officer wasn't disabled at all, and would spoil her rotten!
The young couple's life grew better and better. Shen Nianqing devoted herself to research, producing increasingly astonishing results and eventually drawing the attention of Huaguo's research institute.
The country took his wife away, leaving the cold-faced officer alone at home day after day, going crazy with loneliness!
