Reborn in the ’80s as a Group Favorite Bigshot

A big shot from a research institute in the apocalypse is reborn as a little village beauty in that era.
A few years later, the upper echelons of Kyoto’s elite circles are shaken. The unruly and arrogant Crown Prince of the Gu family has actually taken a fancy to a village girl.
It is said that this village beauty is also the village bully, lazy, fierce, and uneducated, and her entire family is made up of oddballs!
How can a village girl be compared to the young ladies of the upper class? Everyone mocks Song Chu.
However…
Big shots in animal husbandry and planting; a magnate in the catering industry; the founder of an educational institution; the richest person in the country… one after another, they declare, “I owe all my success today to my Little Sister, Song Chu!”
Everyone is collectively dumbfounded: Really? We don’t believe it!
But then, on the same day, the country’s top biopharmaceutical research institute officially announces: “Congratulations to Dr. Song Chu for winning the International Pharmaceutical Gold Award, and thank you to Dr. Song for leading us to become the world’s most advanced pharmaceutical organization.”
This is immediately followed by an article lavishly praising her, along with a photo of her holding the trophy.
Looking at the fair-skinned, beautiful, and exceptionally elegant Dr. Song, everyone’s jaws drop. What happened to the rustic and uneducated village girl? This is clearly a beautiful, cool, and talented winner in life…
At the same time, the Crown Prince of the Gu family, who is also a tech giant, approaches Song Chu: “How about taking responsibility for me first…”

In a world ravaged by the apocalypse, Song Chu, a brilliant but solitary biologist, met an untimely end. However, her story didn’t end there. She awakens in 1975, in the body of a notorious village bully in rural China, a woman with the same name but a vastly different reputation. This Song Chu is known for her laziness, fierce temper, and a hopeless infatuation with the handsome educated youth, Gu Yue.
Adding to the bizarre situation, Song Chu discovers that her state-of-the-art laboratory from the apocalypse has inexplicably followed her, split in half, with the other half now residing within Gu Yue’s mind. To regain her full laboratory and understand this strange phenomenon, she must cooperate with the very man her host body once harassed.
As Song Chu navigates this new reality, she decides to use her knowledge and skills from the future to improve the lives of her newfound family and the impoverished village. She sets her sights on revolutionizing the village’s agricultural practices, starting with an oil pressing workshop and dreaming of larger ventures like a chicken farm and food processing factory. Along the way, she confronts her host body’s past misdeeds, reforms her troublemaking brothers, and deals with the jealous schemes of her former best friend.
Amidst her ambitious plans, Song Chu finds herself drawn to the intellectual and enigmatic Gu Yue. Their forced partnership blossoms into a complex relationship as they work together, sharing knowledge and challenging each other’s perspectives. As Song Chu strives to uplift her village and secure a brighter future, she must also navigate the delicate balance between her growing connection with Gu Yue and her desire to remain independent.
