One-line summary: [The laid-back cannon-fodder wife was supposed to get written out, but instead she ended up with the female lead?]

Su Tangtang transmigrated into a book and became the female lead's cannon-fodder wife.

The book she entered was a romance novel with a male-female pairing. To protect the family estate, the female lead's family raised her as a boy from childhood so she could inherit the title.

Later, the female lead returned from war and fell ill. Her relatives made the decision for her and found her a wife to bring her good luck.

Su Tangtang transmigrated into that bride.

The bride's fate was to cause trouble at every turn, discover the female lead's secret, and eventually be hacked to death by a mob at the roadside.
