Halfway Through the Mission, the System Ran Away

Jiang Ningning stayed up all night reading novels and died suddenly. Bound to a System, she transmigrated into a novel as a vicious female cannon-fodder character who drops out of the story after just a few chapters. To survive, she has no choice but to follow the original plot and seduce her cousin. At last, she reaches the final plot point. The mission is almost complete. Then she can't get in touch with the System. And the cousin she provoked locks her away. This is nothing like the original story! The plot's gone off the rails! System, come back!
