Zhang Yu continued working through her exercises without glancing at Liang Yan, not hearing any movement or footsteps from behind for quite a while.
Zhang Yu kept solving problems without turning around.
Liang Yan stared at Zhang Yu's back for a long time, her gaze complex.
Previously, she had heard her sister say that Liu Xia and Liang Qiang's schoolwork was not good and was worried about their future as the eldest daughter of the family.
But she was merely worried, not daring to bring up the matter of tutoring classes. Even without financial separation from Zhang Dong, she wouldn't dare ask; the tutoring fees for two kids are no small sum.
Later, upon hearing Liang Li propose Zhang Yu tutor the two children, she naturally had no objections; after all, it wouldn't cost anything and would improve Liu Xia and Liang Qiang's grades.
She felt it was just Zhang Yu spending a little bit of time weekly, which wasn't a big issue.
