Twenty years ago, Song Heming was penniless but had two burdensome sons. Because of the promise they made to his wife before she died, Song and Ming survived with their children no matter how hard it was. But before, Song Heming owed money to a "boss" but was unable to pay it back. The "boss" took away his youngest son in anger. When Song Heming raised money to redeem his son, he received news that he couldn't accept - his son was dead. In anger, Song Heming stabbed the "boss" and was later sentenced to jail. Three years later, Song Heming was released from prison, found his son "Song Ke", and left this sad place. Later, Song Heming made a lot of money from business and turned into a "boss" and "entrepreneur". But the younger son Song Jing who died at the time was not actually dead. 20 Years later, "Song Jing" broke into the worlds of Song, Ming and Song Ke due to various things. Many stories of love and hate, joy and sorrow, and entanglement of grudges have occurred in the bustling city.
