The little princess of the Huo family, one of the wealthiest families, was mistakenly switched out nineteen years ago!

Suddenly, the unmarried twenty-year-old Ye Zhizhou had many more relatives, yet it was too late for him to clearly understand the circumstances as he nearly died in a car accident. After that, he somehow managed to survive and was even forcibly bound to a Salvation System.

How is it salvation?

The cliff the protagonist would jump off of, he jumped off of first. The gay s*x the protagonist would have, he’d have. . . . Wait wait, can’t do this one, change it, let me change it.

???: No, you can do this one.

???: Your husband.

Ye Zhizhou: . . . .
