Zhang Yu, studying at the University of Science and Technology of China (USTC), is pleased to be free from the Zhang Family's presence and dedicates herself fully to her studies.
Due to her interests, she also finds time to audit classes in the physics department, resulting in being extremely busy with courses from two majors simultaneously.
On weekends, Lu Jiajia would video call Zhang Yu to ask questions, only to find her either in the study room or the library.
Initially, Lu Jiajia was very surprised, knowing that college wasn't as easy as she imagined, but she didn't expect it to be so busy that weekends had to be spent in the library.
When she found out that Zhang Yu was also attending physics courses, she was completely confused.
Even though she was in a science major, Lu Jiajia struggled a bit with physics, and Zhang Yu chose to study it.
