Su Ming's smile froze. He was a few years older than Yan Shen. When Su Kun's business had been on par with the Yan family's, his family and the Yan family had been neighbors.
At that time, his mother had passed away for a few years, and his father was busy with his business and had no time to take care of him. There were only two nannies at home, and he was in his rebellious period. He was lawless and had done enough damage to his own family, turning his attention to the Yan family next door.
At that time, Yan Shen's sister was understudying with Yan Shen's father. Yan Shen was the only one left in the Yan family, and he looked easy to bully.
That was why, when Su Ming had nothing to do, he would tease Yan Shen. He would only stop when the latter was annoyed. Later on, his family moved to B City. He did not know much about the relationship between adults, so he did not keep in touch with Yan Shen.
