In the "Intersection of Light and Shadow", a top advertising company in the bustling city, Lin Qianxia, a talented but arrogant designer, and her boss and secretly married husband, Shen Mochen, are staging a love-hate entanglement that spans past and present lives. Lin Qianxia, due to the unresolved love in her previous life, has complicated emotions towards Shen Mochen in this life. She is eager to get closer but is afraid of repeating the same mistakes. She often hides her inner shyness and uneasiness with an arrogant attitude. And Shen Mochen, a yandere-like being, has an almost paranoid possessiveness towards Lin Qianxia. He uses his professional status to silently protect her and eliminate any factors that may threaten their relationship at all costs, including concealing their marriage, just so that he can enjoy this forbidden love exclusively. But all this was not so easy to achieve. What happened?
