Just this point alone had aroused Xu Ruobing's suspicions.
Thinking of the words Xu Ruobing had written in the letter, Chu Ning's mouth curled slightly, "Xu Ruobing isn't romantic-minded, and wouldn't think that it was her beauty that made Su Yu fall for her at first sight, causing him to stay at the Xu Family without leaving. She would only suspect that Su Yu had some ulterior motive toward the Xu Family."
With these suspicions, Xu Ruobing had secretly surveilled Su Yu and then made a significant discovery.
Every once in a while, Su Yu would go to a place to meet someone.
This discovery made Xu Ruobing cautious of Su Yu, but she didn't expose him, since the sealing of Shanyang City was about to be lifted. Pretending to go along with Su Yu was the best strategy until her father and the others were released.
If Su Yu were exposed, it was very likely that Su Yu and the people behind him would immediately act against the Xu Family, which could potentially bring disaster upon them.
