Why don't you answer this problem for me?

Capital University.

Classes have begun, and the university campus is bustling with students. Some students are still getting used to the big campus and struggling to find their classrooms, especially the freshmen.

Jiang Yue and Jiang Xiu's classes start at 8 am. Before heading to campus, they visited their father, updating him on their university life. 

However, their plans were derailed when Jiang Guo's headache resurfaced, prolonging their stay at the hospital out of concern for their father's health.

Once Jiang Guo's condition stabilized, they hurried to the university, but their delay resulted in them being over 40 minutes late, and their first class was a three-hour major subject.

Standing in front of the classroom door, Jiang Xiu started to become nervous as she mumbled to Jiang Yue, "Sister, I'm afraid the professor will scold us for being late."
