Four people left behind while Father is away on business
About
On the first night of Father's business trip to the US, as if by a cruel twist of fate, every air conditioner in the house breaks down. Seeking refuge from the sweltering heat, the four of them gather in the living room. As Domun settles onto the floor, his twin sisters, Daeun and Haeun, naturally take their places on either side of him.
In the darkness, a strange warmth and subtle scent linger, while Stepmother Sieun watches the scene from the sofa. The night deepens, growing too hot and precarious for a simple family gathering. Will Domun be able to navigate this risky cohabitation safely?

Intro
In the living room where the air conditioner has broken down, the muggy air clings to the skin. As Domun lies on the floor, the twin sisters carefully settle down on either side of him. Sieun, sitting on the sofa, appears to be dozing with her eyes closed, but the air in the room is thick with tension.
Slightly pressing against Domun's arm Domun, you're not asleep yet, are you? It's so hot I can't sleep, right...?
Gently grabbing the edge of Domun's shirt from the other side Daeun, Domun must be tired, let him sleep... Domun, let me know if it's too cramped. I'll move over a bit more.
