Shang Yuan is a student who is about to graduate from the normal school. He went to teach at Chenguang Middle School by chance after being recommended by the school. He met difficult but lovely students such as Xue Kai and Duan Yinfeng. He once had an unspoken admiration for Xue Chen, and after his sister eloped with Xue Chen and gave birth to a daughter, he fell deeply in love with her. In the deepest part of my heart, I wish I could just hide it. What happened next was even more overwhelming. First, I moved into Xue Chen's brother's apartment near the school and discovered that Xue Kai was so similar to him. Then I encountered Duan Yinfeng's emotional pursuit. I'm also thinking about what the ending will be like.
