In the shadows of the city lies an alley that devours regrets.
Chen Bo, an ordinary young man, stumbles into a mysterious place called Loop Alley on his way home on a rainy night. It is a dumping ground for objects, memories, and sins abandoned by the world. Pick them up, and you can glimpse the past and make wishes come true, but the price is impossible to predict.
His only ability is to “read” the powerful emotions left behind on objects. A lipstick stained with the resolute tears of Xia Lan, a girl he had met only once, becomes his sole clue. To solve the mystery of her disappearance and save himself, Chen Bo has no choice but to search desperately amid countless twisted rules and dangerous “echoes.”
Yet every time he uses “resonance” to peer into the truth, it is like dancing on the edge of a blade, awakening horrors that lie even deeper. As he gradually uncovers the cruel truth of why Xia Lan was forced to leave, he draws closer to the heart of Loop Alley, which devours everything. The only way out may be to become its new “Host”... or perhaps to find the nearly nonexistent “loophole.”
This is a journey to seek the truth on the brink of madness. Every stranger’s regret he picks up could become the grave that buries him, yet each one also illuminates a glimmer of humanity.
