Transmigrated into a 1970s Book: I Have the Aloof Brigade Commander Wrapped Around My Finger

Su Yu is both a rich second-generation heiress and a self-made entrepreneur. She's rich, free, and beautiful, with plenty of handsome men pursuing her. Her life motto is to flirt, never marry, and enjoy her own company.

But she transmigrates into a book set in the 1970s and becomes a disposable character, destined to be caught in bed by a local bully and then forced to bear his children until she's completely broken.

Su Yu: ...I don't get a choice? So where's the man I'm supposed to be caught with?

Yu Mingrui is a test pilot in a special era. He works as both a pilot and an engineer, and has chosen to remain unmarried for life in service of his country's fighter aircraft program.

But one day, while away on a business trip, a young woman barges into his room and grits out, "Either be my lover, or let me go."

Yu Mingrui: ...I don't get a choice? Then put your hands up!

Later...

Su Yu thinks that this man is fierce with everyone but her. He's handsome and in great shape, so why not flirt with him and see what happens? It's not like he'll ever get married.

But things get out of hand. In the end, the man pins her in a corner, his eyes bloodshot as he asks, "Are you really going to keep treating me like your lover? Tell me when I get promoted to husband!"
