Gu Mingxi and Pang Qian were next-door neighbors, classmates, and deskmates. From year-to-year, even when the class seating was rearranged, they would still be deskmates. They grew up together like a pair of brother and sisters despite having different parents; if it was someone else, then their parents would probably have already arranged their wedding.
