Shangguan Yuer's husband—no, now her ex-husband.
After he had signed the papers, he became an ex-husband instead of a husband.
He just wanted to see if this pretty boy could make Shangguan Yuer happy, with no intention of watching the two of them getting it on.
So, when Lin Zhuangguo started to lift Shangguan Yuer's skirt, he promptly signed, quickly leaving the room.
He didn't want to get his eyes burned by watching them go at it.
"He doesn't want to watch? Fine, let's get to it. From now on, I'm your woman," Shangguan Yuer thought her ex still enjoyed watching her with Lin Zhuangguo.
Turns out he had hurriedly left, probably to cry in the bathroom.
Without her connection, his company's performance might suffer a loss.
"Your tastes, how come they're so heavy?" Lin Zhuangguo picked her up and gave her a Rear-Insertion Style against the hotel window.
