Genius perfumer Su Wan once amazed the world with a perfume called "Chang Jian", but after a bizarre car accident, she lost her sense of smell and part of her memory. She fell from the altar and became an ordinary librarian incognito. Three years later, when she thought her life would forever be spent peacefully in the shadow of the bookshelf, a man carrying the scent of "First Meeting" perfume - Lu Jingshen, the president of a multinational technology group, forcefully broke into her world. He pressed forward step by step, weaving an invisible web with familiar yet unfamiliar tenderness, trying to awaken her dusty past. However, as the memory fragments were pieced together, Su Wan discovered that the car accident was not an accident, and what she lost was not just her sense of smell and love. When business intrigues, family feuds and tampered memories are intertwined, how should she trust the lover in front of her? Should he indulge in the perfect illusion he constructed, or break through the fog and find the complete but possibly cruel truth? At the junction of love and lies, every heartbeat may lead to an abyss.
