Nie Dongyuan had two regrets in this life, the first was that Nie Yusheng did not become a businessman, but became a doctor of the heart, and the other was that he had not waited for Nie Yusheng to get married and have children. In Nie Dongyuan's view, these two regrets were caused by Tan Jing.

After Nie Yusheng knew that Tan Jing's father had heart disease, he decided to become a doctor and personally cured Tan Jing's father's illness. Although the two broke up later, Nie Yusheng still became a doctor as he wished. He has not had a girlfriend all these years because he can't forget to talk about Jing in his heart. Nie Yusheng had been saying that there was only hatred for Tan Jing, but just after the two met again, Nie Yusheng's subconscious eyes could not deceive people.
Especially after knowing that Tan Jing raised money day and night for the sake of Ping Ping's illness, Nie Yusheng ignored the criticism of his leaders and left the opportunity to try new technologies to Tan Jing. Unfortunately, because of Sun Zhijun's trouble, Pingping's surgery was completely ruined, and Pingping's current physical condition can only be routinely operated as soon as possible, otherwise he will not even be able to survive at the age of ten.
Although Nie Yusheng was distressed to talk about Jing, he also felt that this was Tan Jing's retribution, and did not realize that Ping Ping looked similar to his own when he was young, but nie Dongyuan began to doubt Ping Ping's identity after seeing Ping Ping twice, especially after knowing that Ping Ping was Tan Jing's son, he was more certain of his conjecture. After finding someone to do the paternity test, Nie Dongyuan was very surprised by the final result, because PingPing was his grandson, which also meant that the Nie family finally had a queen.
For Nie Dongyuan's age, money and fame have long been despised, and Nie Dongyuan knows his body well, so he has been urging Nie Yusheng to marry and have children earlier, so that he can hold his grandson in his lifetime. Now that Pingping's identity has been exposed, Nie Dongyuan's wish has been realized, but even if Pingping is Tanjing's son, Nie Dongyuan is still dissatisfied with Tanjing, and even feels that Tanjing is too selfish, and even hides Pingping's life from them.
At this time, Nie Yusheng naturally knew everything. Nie Yusheng originally thought that Tan Jing had not only abandoned himself, but even abandoned their children, but the existence of Ping Ping at this time also indirectly confirmed Tan Jing's feelings for him. Nie Yusheng was thinking about how to reconcile with Tan Jing, but Nie Dongyuan knew that his time was short, and even threatened Nie Yusheng before his death, letting Tan Jing leave and take back the custody of Pingping, on the one hand was his beloved woman, on the other hand was his father who was about to leave, at this time Nie Yusheng was in a dilemma, he did not know how to choose, after all, he and Tan Jing had missed seven years, and he really did not want to continue to miss.
