Since Ye Liu wanted to teach Old Master Zi a lesson then Yu Dong would naturally help him get what he wanted. She was not one of those tyrant CEOs who would do anything that her lover wanted but even she could not withstand how arrogant Old Master Zi and his family were being. If that was the case then they could not blame her for teaching them an itty bitty lesson.
Ye Liu heaved a sigh of relief when he heard Yu Dong say that she was going to teach a lesson to Old Master Zi. He hated how that old mer was causing trouble for his brother and was jumping around like an annoying grasshopper.
He was not petty but someone as disgusting as Old Master Zi really needed to be taught a few lessons about morality and human behaviour lest he continued to act like a beast.
