The sober female strategist in the world VS the hard-mouthed and soft-hearted female strategist.
Su Jin is disguised as a cannon fodder princess who poisons the villain, and she starts by pouring poisonous wine down her throat.
She relied on "I know where the late emperor's edict is" to survive, and then signed a three-year contract marriage with the villain Shen Du - she helped him break the situation, and he kept her alive.
She thought she could cheat by holding the original script, but she discovered that the author of the book had stopped writing it long ago - because the characters had come to life, the plot was messed up, and the world was growing on its own.
She can only rely on herself. Open a restaurant, set up a chain, use modern business thinking to carve a bloody path in ancient times, and at the same time make this hard-mouthed and soft-hearted villain blush until his ears turn red.
On the surface, Shen Du was decisive in killing, but behind his back, he held hidden stakes for her, sent lanterns, and said "If you are afraid, you can keep holding on" on a thunderstorm night.
When two people who refuse to accept their fate decide to work together, the ending of the story can only be written by themselves.
