When Zhuang Nainai heard Si Jingyu defending her, she was stunned.
People like Lin Xi'er and Su Yanbin were only her friends. In front of them, she had never shown her vulnerability.
On the other hand, Si Jingyu… was older than her and Si Zhengting by three years. Having lived with her for a period of time, Zhuang Nainai really treated her like family.
For this reason, she was even more afraid — afraid that Si Jingyu would misjudge her and hate her because of Mother Ding's accident.
When Si Jingyu was approaching her just now, she looked extremely indignant. However, she did not think that her indignation was targeted at Si Zhengting.
Instantly, Zhuang Nainai's eyes welled up and her nose stung, as if she had just seen her parent!
Looking at Si Jingyu, she called out with trembling lips, "Sister!" Thereafter, she hugged her with tears running down her cheeks suddenly.
