She is Xiao Min, a billionaire who was born with a silver spoon in her mouth. Her life is filled with exquisite rules and her father's expectations, but she always longs for a hint of real fireworks late at night; he is Long Yun, a poor boy who repairs cars in a village in the city to make a living. His days are wrapped in the smell of engine oil and the pressure of survival, but he uses his paintbrush and kindness to his neighbors to hide tenderness in his poverty.
An unexpected bicycle accident caused Xiao Min, who was wearing diamond sandals, to crash into Long Yun's world full of wrenches and sketchbooks. She looked at his side face when he was helping his grandma move the paper shells, and it was like seeing stars polished by life; he saw her seriousness when she squatted on the pony to watch the sunrise sketch, and discovered that there was an unknown loneliness hidden under the skirt of the daughter-in-law.
When the fragrance of gardenia meets the smell of engine oil, and when the lights of the rental house illuminate the floor-to-ceiling windows of the mansion, the class gap gradually dissolves through repeated trials. Xiao Min found freedom in Long Yun's fireworks, and Long Yun saw hope in Xiao Min's heat. This is not a simple love between a rich man and a poor boy, but an encounter between two souls across the world - she redeems his tiredness of life, and he lights up her disciplined life.
