Alone

Pim and Ploy are conjoined twins joined at the stomach. Pim is sweet and caring; Ploy is harsh, jealous, and cold. During a long hospital stay, the two meet Wee — a boy who falls in love with Pim and confesses it openly. Ploy responds by refusing to leave her bed, pulling them both down with her jealousy. In a moment of fury at having her happiness held hostage, Pim demands the separation surgery they'd always been told was possible. What follows is not what either of them intended: before the surgery, Ploy strangled Pim in a jealous rage, killing her. To save Ploy's life, doctors performed the separation anyway, cutting her free from Pim's corpse. Ploy recovered. And then she did the only thing that might let her survive what she had done: she became Pim. She took Wee. She moved with him to South Korea and built a life on a grave, burying the truth so deep she nearly believed it herself.

Years later, a phone call from Thailand: Pim's — Ploy's — mother has had a stroke. Ploy and Wee return. From the first night back in the family house, something is wrong. Figures at the edge of vision. Sounds that have no source. Objects that have moved. The haunting escalates in ways that can't be attributed to stress or guilt — something is physically present in the house, moving through it, making itself known. Ploy recognizes, in the way you recognize a thing you've refused to think about for years, whose face it wears.

When Wee visits Ploy's mother alone, she tells him what she knows: the woman he married is not Pim. Pim died before the surgery. The ghost haunting the house is Pim — the wronged sister, the murdered one, returning to reclaim the life Ploy took from her.

Wee confronts Ploy. The truth in the open does not diffuse into something manageable — it ignites. A fight breaks out in the family house and fire starts. Wee throws a shelf onto Ploy to escape. Trapped beneath the burning wreckage, Ploy looks up to find Pim's ghost standing over her. Pim smiles — not in cruelty, but in something close to peace — and holds Ploy down as the house burns around them. Ploy dies.

Wee visits the twins' grave. He takes out the necklace he gave Pim in the hospital, the one that was always hers, and sets it against the tombstone.
