Gu Tiantian buried her head in her books, unaware of Zhang Lan's thoughts.
In fact, she even forgot to remind Bai Chenyao to come back early before lunch.
According to the usual schedule, her last class in the afternoon ends exactly at 5:30.
Since all her attention was on the books, Gu Tiantian didn't notice the commotion in the living room outside.
But Zhang Lan, already having ulterior motives, became alert the moment she heard noises outside.
She took a careful glance at Gu Tiantian, and after confirming her seriousness in studying, her mind started to become active.
As if considering something, Zhang Lan suddenly abandoned her intention to look outside and focused on staring at the study materials she brought.
Picking up a pen, she began to make annotations.
Simultaneously, she quickly highlighted key sections and took out notes made previously when inquiring about Gu Tiantian's situation, comparing them one by one, evidently deciding to tailor her teaching accordingly.
