It was not that Lou ruofu had never suspected Liao Wei's identity, but she had known him for a long time and had been in contact with him for a few years. Moreover, Liao Wei's identity had been recognized by the Jing family. No one would have thought that he was Jing Rui's substitute.
Of course, Liao Wei did not say that Jing Rui was a fake. He was the real one, in case the Lou family found out that he was the fake one.
He only said that he was just putting on a show with Shuyin and told Lou ruofu about Shuyin's identity. He made it clear that he was afraid of Shuyin's strength and the Virus Research Institute's strength.
Liao Wei had been doing very well recently. He slept in the day and played with women at night. He used Jing Rui's face to get in touch with several young ladies from small families, and made them cry and beg to marry him.
