But the female assistant, Wang Jing, was unaware that Su Xihe had long known she was eavesdropping outside the door.
To find out whom the female assistant was working for, Su Xihe suddenly called her back into the villa.
While pretending to discuss a salary increase with the female assistant, Su Xihe made her a cup of hot tea.
The unsuspecting assistant drank it, only to find out it had been spiked with an aphrodisiac.
By the time Wang Jing realized what was happening, she was flushed and aroused, the drug taking effect.
Su Xihe interrogated Wang Jing directly, asking who she was working for and why she was spying on her and her daughter.
Wang Jing was terrified and trembled as she explained, "It was… Miss Su Wanqiao, she asked me to help… to spy on you. She sensed that Lin Shuang was getting too close to you and thought it was abnormal..."
On hearing Wang Jing's explanation, Su Xihe's beautiful eyes narrowed.
Was it Su Wanqiao who had instructed her?
