When she heard Yu Chenshi's voice, a sense of unease welled up in Ling Tianya's heart. Yet, she didn't tell Yu Chenshi the truth.
Yu Chenshi was innocent, and Ling Tianya didn't want her to have to agonize over the wrongdoings committed by Yu Meizi in her old age.
Besides, Ling Tianya genuinely didn't want to lose Yu Chenshi. If Yu Chenshi knew the truth, she would definitely feel guilty towards Ling Tianya and would not want to trouble Ling Tianya again. She might even disappear from Ling Tianya's life forever. That wasn't what Ling Tianya wanted.
Ling Tianya promised to investigate the matter while comforting Yu Chenshi and telling her not to worry anymore.
Ling Tianya told Yu Chenshi that Yu Meizi had quarreled with Zhang Chao and thus had left with Zhang Zihao.
