! When an old object carries powerful emotions such as regret, resentment, or longing, it can gather into a “shadow” on rainy days. It might appear as a vague human silhouette, a repeated sound, or even a brief “memory replay.” Ordinary people cannot see these shadows, but they can still be affected by them, suffering nightmares or losing control of their emotions. A rare few, such as Su Yan, can see them. If they actively “respond” to a shadow, they are drawn into an “obsession illusion” and trapped in the memory of the object’s owner.
