Joe and Ah are good friends, and Joe is a computer expert, so he promised to help A Jiu and installed bugs for the four brothers Lu, ready to eavesdrop on their secrets. Joe helped Ah completely out of the relationship of friends, but Ah did it entirely because he liked Lu Yongyu, a former boyfriend and girlfriend, but Lu Yongyu only had interests in her heart, and she used A Jiu more.
Ah was carried away by love, but Joe wasn't. When he learned that Lu Yongyu and other Lu family members were hiding deeper interests and conspiracies, he chose to stand on the side of justice.
Although Azu was kept in the dark and had been in prison, he yearned for the light in his heart, helped villagers bullied by real estate developers many times, and finally fell in love with Yuehua.
