She did not think too much. It was Teacher Liu who worried too much.
"It's good if you think that way." Teacher Liu sighed with relief. Being a teacher for so many years, he had seen many students who stirred up trouble because of competing with other students to be the top student. Some of them felt the stress at being overtaken by others and pushed themselves to get back on the tracks, but their grades worsened instead. They used to be top students but ended up to be students with fluctuating results.
Teacher Liu was worried that this time was no exception. Hence, he told Qiao Nan beforehand, lest she went down a blind alley.
Besides, Shi Qing also came at an inopportune time. Teacher Liu was busy doing revision with the students in class one and she transferred to their class at this time.
