Did My Male Lead's Big Brother Divorce Me Today? (Transmigrate into a Book: Republic-Era Military Academy Romance)

Yun Yuan never dreamed that she, a 21st-century female agent, would transmigrate to the Republic of China era and fall hopelessly in love with Shen Tingbai. She gave up every bit of her status and standing in that era for him, but never won the slightest affection from him. Only after she died did Yun Yuan learn that she had transmigrated into a book called Arsenal Military Academy. The man she loved was the older brother of a male supporting character in the book, while she was just a passerby who had never even been mentioned.

Shen Tingbai, you bastard! In my last life, I gave up everything and worked so hard to take care of your parents, while you played the devoted young master in Shunyuan. Why are you, Young Master Shen, the only one allowed to pursue true love? Why can't I, Yun Jiao, go find myself a little wolf dog? I want a divorce. I want it today.

Shen Tingbai, if you think I'll be your free housekeeper again in this life, dream on! You laughed at my taste, my education, called me a country bumpkin, and said I wasn't good enough for Shen Tingbai? How about a 21st-century female agent? Hah! I gave up being a powerful underworld boss to play his old nanny. Since you all object, then I'm done!

The scumbag Shen, reborn: Yuan-yuan wants to divorce me? Impossible. Yuan-yuan loves me most. Yuan-yuan, Yuan-yuan, I want to have babies with you!

A versatile female agent from the 21st century transmigrates, first to the Republic of China era, then is reborn a second time with her memories intact. This is a proper transmigration-into-a-book story, except that unlike other stories of this type, the original book is not fictional: the book and the TV series both really exist. However, this story has basically nothing to do with either the original book or the TV series, so even readers who haven't seen them can jump right in.

Theme: A female supporting character transmigrates into a book.
