A sincere relationship developed between the two, and they have been together for many years.

In the end, she can't get over her son's persistence and determination, and the marriage is finally settled. However, it didn't take long for the peaceful life to end before Zhang Heming's childhood sweetheart Zhuo Huina (Wen Mengyang) began to appear next to Zhang Heming again and again. Amid suspicion and distrust, the relationship between Su Jin and Zhang Heming was cracked.
