He is Lu Jinyan, the indifferent and taciturn CEO of the Lu family who is in charge of the business empire. He has severe mysophobia and violent tactics. He is the business emperor who is respected by everyone in Jiangcheng. He has a heart as cold as ice and has no weakness. She is Su Wan, a cleaning lady who struggles at the bottom to save her seriously ill brother. She is as humble as dust but as tough as weeds. She works with her head down in a skyscraper, only seeking a corner of stability.
An unexpected water damage caused a speck of dust to fall into his glass tower high above. He should have despised and expelled her, but instead he fell in love with this smoky cleaning lady. He made things difficult for her, paid a lot of money in advance to save her brother, and surrounded her. He was domineering and paranoid: "Su Wan, you are the only one allowed to clean the 60th floor, and you are the only one allowed to be close to me."
Rumors from the company, ridicule from celebrities, obstruction from the family, class gaps... All obstacles came at her, and she felt inferior and retreated, but he held her hand tightly and refused to give in. "Who are others? What is identity?" "The person I, Lu Jinyan, love, even if he comes from the dust, is worthy of all my tenderness and power."
When the frozen heart is melted by her warmth, when the humble she is illuminated by his blazing flame, the dust and the blazing flame will eventually become entangled to the death and never be separated again. This is an ultimate fall across classes, and also a deep love that saves each other.
