So many things had happened recently. She had not been to school for many days.
This morning, Professor Wang gave Jian Dan a call. He said that one of the researchers he was working with had something on and left at the last minute, so he needed an experienced person to help.
Hence, Jian Dan rushed to the campus after the professor's call. Before she left, she even told Chu Liyuan that she might need to stay on campus for a few days because this project was rather urgent. She would probably stay up late for the next few days.
Although Chu Liyuan was very unhappy when he heard that Jian Dan was going to be away for a few days, he thought about how he could not always keep Jian Dan by his side; she also needed her own pursuits and space. Moreover, it was a special period now. It was a little torturous to sleep with Jian Dan every day!
