In order to escape from her ex-husband, A-Long, Lili moves to an old apartment by the sea and discovers a living sofa there. After fixing the sofa's broken limbs, the sofa becomes affectionate with Lili like a dog.

A-Long finds Lili's apartment and demands money from her. When the two of them argue, the sofa suddenly swallows A-Long whole, leaving no trace behind. The sofa has consumed Lili's fear, allowing her to sleep peacefully at night. However, when her child comes to visit her, the sofa becomes a new source of fear for her, as she is afraid that her child will also be swallowed.

Lili decides to take the sofa to the beach and burn it at night.
