If she knew the truth about Feng Tianyi's accident, he feared that it would only make her hate him. So it was better if she didn't associate herself with him at all. This would also protect them from being suspected by the Zhang family.
If Zhang Xianzhe found out that Zhang Jiren knew that he was Tang Lingjun, there would be a chance for his plans to be derailed and Li Meili's life would be in danger. The less people knew that they knew each other, the better.
"Fine. Let it be that way." Tang Moyu agreed with him.
If Zhang Jiren believed that she was that weak, that she couldn't protect herself and her loved ones, she didn't need to waste time to explain her side, her actions would prove it. She would never allow herself to shed tears because of the Zhang family ever again.
