"What? Did you finally decide to stop going back and send a letter to him?" Zhu Zhengting's remark was sarcastic, but he meant it for real.
Over the weeks, Yun Shu received many letters from Bai Yunxian, but never replied to any of them. And he even forbade others to write or talk about his condition, not even to Zhu Zhengting.
It was out of pity that he wanted to write Bai Yunxian about how Yun Shu was fairing, but seeing how he frequently was facing the dangers and getting injured, Zhu Zhengting had to postpone the thought for now, since telling all the things happening here would only make Bai Yunxian anxious.
However, no one aside from Yun Shu's closest associates knew that he's been frequently visiting the estate, going back and forth between the two places at night, just to see how Bai Yunxian has been doing.
