Tian Xiaomai, Angelababy, an urban white-collar worker, stands on the brink of walking down the aisle with her fiancé Sheng Zan, Zhang Chao. The ceremony halo of happiness shatters the moment his father’s death in the line of duty echoes through the family, casting a shadow over the planned celebration. As Tian sorts through a box of her father’s relics, she uncovers his investigation notes—fragments of a case that hung in limbo for more than ten years. The deeper she digs, the more the past insists on resurfacing, pulling at her heart with memories of a first love she thought she had left behind.
This buried mystery pulls Tian into a thread she hadn’t expected to pull: her first love, Qiu Shou, [Ethan Juan], and the tenderness of a past chapter that never fully closed. Around this fragile memory, Tian learns of an online storefront named “Witch District” that claims to sell almost anything—even memories of love. The discovery is unsettling, yet irresistible, and it nudges Tian to explore whether love can be bought or if it’s a truth that refuses to stay buried.
Her best friend, Qian Ling, [Rayza], whispers about the strange marketplace and the strange way it intertwines memories with current peril. When Tian buys a mysterious purple scarf connected to the unsolved case, a cascade of accidents follows—strange coincidences that suggest the old murder is not really a thing of the past, but a current, growing danger. The scarf seems to braid the fate of Tian’s present with the orbit of her youthful love, pulling her into a web where memory, guilt, and desire are powerful forces.
Driven by a mix of curiosity and necessity, Tian begins to pursue the clues that long ago eluded an answer. She navigates a city who’s rhythms are mirrored by the online whispers of Witch District, seeking out threads that might lead to Qiu Shou and reveal how his life and the murder case are entangled. With each clue she tracks, the distance between what she believed to be true and what actually happened grows shorter, as if the past is rewriting itself before her eyes. The investigation becomes a personal reckoning as memories bleed into evidence, and what seemed like a closed era starts to alter the shape of Tian’s future.
As the investigation widens, Tian Xiaomai realizes that the love she has held as a memory is not simply a private recollection but a piece of a larger puzzle that could unlock the whole mystery. The path toward truth makes her question loyalties and confront hidden connections, and the closer she gets to the truth, the more she discovers that Sheng Zan’s family sits at the heart of a conspiracy that ties the present to the past. The boundaries between affection, family duty, and the murder case blur, forcing Tian to decide how much she is willing to risk to uncover what truly happened all those years ago—and what it means for her own life and the life she hoped to build with Sheng Zan. The journey is dangerous, revealing, and heartbreakingly intimate, and it poses a question at every turn: can memory become a key to justice, or will it imprison the living in a story that never truly ends?
