A childhood friend who had been missing for two years suddenly returned, but his temperament changed drastically. Not only did he ridicule him, but sometimes he acted as if he didn't recognize him. Gu Changjun expressed his confusion. But he still decided to protect Wen Zichang, just like he always protected himself before he disappeared. Moreover, he must know, he must know the reason why Wen Zichang became like this!
After Gu Changjun shamelessly pestered Wen Zichang for a period of time, Gu Changjun vaguely felt that Wen Zichang might have encountered an unsolved case that was difficult for him to solve. And after he accidentally discovered a certain secret about Wen Zichang, he became even more eager to know what happened during the two years that Wen Zichang disappeared.
This article is a serious drama, there is an emotional line but it is not the main line, so it is not considered a romance. Reasoning is the main thread.
