A social status worth ten billion yuan; but with an unconscious husband, he was unable to withdraw any money. Tang Wan held the empty position of the First Gentleman, but was, in fact, a poor man.

In order to secure his future livelihood, Tang Wan was bound to the “Earth Pet System” and returned to his old business, with the goal of saving money, getting a divorce, and looking for a second spring!

The pet shop soon became famous in the interstellar world, and the whole universe lined up to be cat slaves~

Tang Wan reached out and pushed him down on the bed: Open what eyes, quickly close them.
