Big Sister, I'm Very Useful

The chat page was filled with messages she had sent to Xiao Yize before she left the classroom at around 11:30 a.m. today.

At that time, she had added Xiao Yize on WeChat through the Class 1 group chat. Xiao Yize had probably agreed immediately because of her big sister.

Later, she saw Cai Jian bringing Yao Bingxue to the office building, so she wanted to follow him. When she saw Xiao Yize standing at the window of the corridor on the second floor of the office building and waving in her direction, she stopped.

Xiao Yize was the vice-principal of First High School. It was perfect for him to handle the teachers' ethical questions.

Moreover, although the original book did not explicitly mention the male protagonist's alias, there were hints everywhere that he was working for the country. In many plots, he had a close relationship with the police.
