*Xu Xinyi woke up and had obtained a system, the system told her that she was a female partner with a miserable/desolate end.

In order to prevent this ending, Xu Xinyi driven by the system, worked diligently on what a female partner should do.

Yi Yang couldn’t tolerate it anymore/at the end of one;s patience, and at last mentioned divorce.

Xu Xinyi’s heart felt ecstatic as she put the divorce agreement in front of her husband and with a sorrowful, heartbroken look on her face waited for her husband to sign.

—“Hurry up! Sign quickly! I can finally leave this darned place!”

Suddenly Yi Yang who could hear Xu Xinyi’s thoughts threw away the pen and said, “Not leaving.”

***

Ever since Yi Yang discovered that he could hear Xu Xingyi’s thoughts, he found that his wife kept kissing up to him and saying she loved him but in her heart she would laugh at that.

She loved him on the surface.

“Husband, you are so nice, I love you very/so much ah!”

—“I won’t be spending the rest of my life with this arrogant man forever, will I? I am the most wretched woman in this world!”

She yelled at Yi Yang: where am I not good! Tell me! I can still change! Wont that work then?
