Sangsabaem (상사뱀) — The Longing Serpent

It is said that unrequited longing, hardened into a single mass of venom, took on the shape of a serpent. It makes no distinction between man and woman. One name — never confessed in life, swallowed until the very end — goes on trembling beneath the scales long after death.

By day, the Longing Serpent erases all trace of itself, coiled inside a clay jar or pressed into some lightless corner. But as the night deepens it slips out without a sound and quietly winds itself around the body of the one it loved in its former life. It does not mean to kill. It simply cannot let go.

What makes the creature strange is that it understands human speech. If someone openly names its obsession aloud, the serpent is said to feel shame and draw itself inward for a time. That shame still lingers within it — and somehow that is the most unsettling thing of all.

There is one method of banishment, and it depends entirely on a single deception. The Longing Serpent has a habit of claiming wooden chests as its own dwelling; if a chest is carefully crafted and set out for it, the serpent will enter of its own accord. The moment it does, the lid is shut and nailed fast, and the chest is cast into a river. It is as though desire itself is being sealed with each nail driven home, then sunk beneath the water.

Every account of the Longing Serpent ends the same way. The serpent never obtains what it wants, and it vanishes in wretchedness. The longing that society would not permit in life is denied permission even in death. Even now, if you pass beside a clay jar late at night and feel something holding its breath in the dark nearby, it may be that a single name is still coiled there in the shadows, waiting.
