Lin Zhu did not know why Yin Xun asked him to stop Yin Mo, nor did he understand the deep hatred the two sisters had. He only knew that the company had a rule that prevented Yin Mo from entering. This was something that every employee knew.
The reason he chose to inform Yin Xun was actually for his own selfish reasons. He wanted to attract Yin Xun's attention so that he might get more work opportunities in the future.
"I'm sorry, Miss Yin Mo. If President Yin does not come, you cannot leave," Lin Zhu repeated. If he let Yin Mo go now, it would be equivalent to telling Yin Xun that he was incompetent.
When Yin Mo saw that Lin Zhu was determined to wait for Yin Xun to arrive, she immediately panicked. This matter could not be discovered by Yin Xun, or else everything would be over.
