Cui Xiaoyu is from the Astronomy Department of the Science and Engineering College; he enjoys studying stars.
Nangong Na is also from the Medical College, like Yu Chen, but she studies nursing. By the way, the Medical College and the Science and Engineering College are located at the southwest corner and northeast corner of the campus, respectively.
Furthermore, the standard four-person and six-person dormitories are concentrated in the southern area of the school, but the two-person dormitories for girls and boys are located in the northwest and southeast corners of the school, respectively.
In summary, although everyone is studying at the same school, they're actually quite spread out. With different majors, even within the same college, unless intentionally gathering, it's not easy to meet up regularly.
