Tang Mo, a Qiye Club owner who is cold and lonely on the surface but passionate in his heart, runs a mysterious shop that is only open for seven hours at midnight. He has a special ability - he can see the "halo of luck" in everyone and change the trajectory of other people's destiny by sharing his secrets.
When the vicious female supporting character Lin Ruyan broke into his shop with a black aura all over her body, Tang Mo knew trouble was coming. This wealthy lady, who looks glamorous on the outside, hides countless dirty secrets in her heart. She set her sights on the city's destiny core - an ordinary boy named Chen Hao who was about to awaken his inheritance.
Tang Mo was forced to get involved in this battle for luck. He discovered that every time a person in his gang changes their destiny, they will receive a "fragment of luck", and these fragments are piecing together a surprising truth: standing behind Lin Ruyan is the "Dark Curtain" of the luck robbery organization, and everyone in this city is a pawn on their chessboard.
During the day, he is an unkind and cold shopkeeper in the eyes of his neighbors; at midnight, he is the guardian of luck walking in the darkness. When secrets began to be exchanged and fate began to be rewritten, Tang Mo discovered that the biggest secret was hidden in himself - he was the real son of luck in this city.
