The two made plans to go together over the weekend, but on the day itself, Xie Ying'an was dragged off on a business trip by Professor Qian.
Since Xie Ying'an's junior year, whenever Professor Qian went to another school for exchange or on a research trip, the favored student he brought along had become him.
This business trip was a bit longer than previous ones, and they hadn't returned even by the eve of the National Day holiday, after nearly a week away.
The night before National Day, Qingran attended the birthday party thrown by a senior in the same lab.
Before leaving, she sent a WeChat message to Xie Ying'an to update him on her whereabouts.
This was something Xie Ying'an had requested after they got together; both parties must inform the other if they were attending a dinner or similar events.
Xie Ying'an himself had indeed done so.
Guessing that Xie Ying'an was busy, there was no reply from the other end.
