His wife gave it to him

Obviously, Wen Huihui must have stolen the notebook and given it to Shen mengfang.

She was a little confused. Was this notebook something important? She flipped through it and saw a conversation between her and Li Sheng. Then, she suddenly realized.

"I'll go to your house tonight?"

"Are you really going? Or did Yingluo ask me to cover up the lie again?"

"I'm really going."

Song ran suddenly felt a sense of fear. Yes, she had been careless. She had been too outspoken and left such an important piece of evidence in the classroom.

Wen Huihui and Shen mengfang were already looking for her mistakes with a magnifying glass, but she had personally handed the evidence of her negligence to them. There was no reason for them to not use it.

She tore off the 'evidence' page, burned it, and flipped through it again. There was nothing else she could use against her conversation with Li Sheng, so she put the notebook away safely.
