Last year, on this very day, within this doorway, a maiden's face glowed red beside peach blossoms. Now the maiden's face is nowhere to be found, yet the peach blossoms still smile in the spring breeze. An unexpected encounter last year led Gu Jibai to find the woman who had appeared in his dreams. Because of his arrival, Su Taoluo was left with a lingering illness and could no longer remember anything about him. With just a single fragrance, she can identify origins, distinguish truth from falsehood, and uncover the secrets others conceal. She has forgotten him, while he carries a heart full of unspoken words and returns again and again, unable to resist, unable to restrain himself, and full of regret, swallowing the words he should have said while doing everything he should have done. Yet she can identify everyone in the world by their scent, except for one person: the man who was once the love of her life.
