A scheming, sinister prince who blushes easily & a transmigrated-into-a-book, lustful, straight-laced Miss Bai
[One-on-one, devoted couple + transmigrate into a book + System + sweet romance + winning his heart]
Shen Jinyin transmigrated, born into the world of a novel as its vicious supporting female character.
Seventeen years ago, the System told her to follow her character’s role and the plot all by herself. All she had to do was act arrogant, domineering, and impossibly spoiled.
Seventeen years later, she only has to complete the System’s final three major tasks. Then she can return to the modern world with one billion in cash and countless treasures of gold and silver.
For a lifetime of financial security, she resolutely sets out to save the cannon fodder, win the second male lead’s heart, and help the male and female leads get together as soon as possible, before making a triumphant return home.
Yan Qing is the Crown Prince’s brother, though they share neither father nor mother. He has endured scorn and humiliation since childhood, turning him into a sinister, patient man.
Everyone fawns on the powerful and tramples the weak. He is determined to claim the throne, using the medical and poison texts taught to him by his birth father to win people over and plant spies.
To secure support for his ambitions, he sets his sights on the power wielded by the Grand Princess’s family. But the Princess’s daughter is infatuated with the Crown Prince, so Yan Qing plots against her.
To him, Shen Jinyin is a spoiled, simple-minded young lady, merely a tool to help him rise to power.
But he discovers that, without even realizing it, she has become the only person in his heart and on his mind.
Yet on the day he ascends the throne, she is determined to leave.
[Content warnings: 1. A Yin has a short temper and can be unreasonable. 2. Yan Qing loses all his sense when it comes to A Yin and becomes completely love-struck. 3. They fall for each other for “no apparent reason.”
4. The mission plot takes up 90% of the story, with an emphasis on winning his heart.]
It's okay. How can I put it this way? The female protagonist is straight and the male protagonist is a bit emotionally innocent. The plot should be somewhat parallel. I'm still not sure after looking a little bit.
