Seven years ago, a sudden fire burned the dreams and love of talented perfumer Lin Zhixia together. She lost her sense of smell and her beloved, firefighter Chen Jin. Everyone thought that Chen Jin died in that rescue. Lin Zhixia left her hometown with endless regret and a broken heart, sealing up all the memories about the smell. Seven years later, she returned as a senior psychotherapist, specializing in post-traumatic stress disorder. During an emergency psychological intervention, she met a taciturn man with distant eyes - Lu Xiao. He is a fire captain with outstanding merit, but he is entangled by the nightmare of the past and has blocked all emotions. When she tried to pry open his dusty heart, she smelled the familiar smell of cedar and flame intertwined on him that only belonged to Chen Jin. It turns out that he is the lover she thought was dead long ago. However, reunion is not the beginning of redemption, but the prelude to another storm. The tampered memories, the hidden truth, and the seven-year gap between the two pushed them once again into the abyss of fate.
