Chen Ji transmigrated into a book.
In the original story, Ye Yan was a mysterious fish.
As a fish, he knew far too much, which made his life miserable. He was either getting stabbed or on his way to getting stabbed. But he just wouldn't stay dead, since he was the protagonist, after all.
Then Chen Ji learned that her mission was to stab the protagonist, Ye Yan, to death.
In this book, where the protagonist gets put through hell, she had to face an unkillable cockroach of a man. As a law-abiding citizen of the 21st century, this was without a doubt an impossible task.
So what could she do? She had to use force!
Send her tools to do it. When they were gone, do it herself!
As she tried to win his heart while guarding her own, Chen Ji inevitably lost her heart.
So what now? Turn this world upside down!
When she tore through this cruel dream, she found an even crueler reality beyond it. If reality was a book, then the dream was its prequel.
To Ye Yan, Chen Ji was the god who saved him. Chen Ji had no idea she meant so much to him. She had only read a book and fallen in love with its protagonist. Her affection came even sooner than her transmigration mission.
(A touch of ensemble cast, a growing-up-together romance, female-led relationship)
