Seeing that Mo Shangjun had no intention of going back, Lin Mao didn't try to persuade her but stayed with her, waiting under the dormitory building.
During this time, Lin Mao noticed that Mo Shangjun wasn't idling; she was holding a notebook, sometimes staring in the direction of the dormitory, sometimes writing and drawing in the notebook.
After a few rounds of this, Lin Mao finally couldn't resist asking, "What are you doing?"
After writing down a name, Mo Shangjun stopped and said, "Training my instantaneous memory."
"What?"
Lin Mao didn't quite understand what Mo Shangjun meant.
Mo Shangjun shook the notebook in her hand, then tossed it to Lin Mao.
Lin Mao raised his hand to catch it and looked down out of curiosity, only to see densely packed names and dorms, leaving him dumbfounded for quite a while.
