A silent, post-apocalyptic world where the roads and skies are frozen in blue and white. In this world, anyone who inhales the air will have their lungs freeze, gradually losing the ability to breathe.

So Guest and Sera are shut away in their house, just the two of them. However, there are limits to living in this world; eventually, the electricity will stop, and their lungs will freeze, ending their breath.

Thus, humanity faces an absolute, biological end due to the spreading cold.

They can no longer leave the house, and there is nothing left to do. Even memories and dreams will eventually freeze solid.

The two of them look at the scenery outside, terrified, repeating shallow, white breaths of hyperventilation.

Today, they eat mandarin oranges at the kotatsu, make corn soup, and cry knowing the next season will never come, reminiscing only about the seasons that have passed.

Then they eat, and they sleep. A cycle of repetition.

【To Guest】 If you grow tired of this life, you might try opening the window.

【If Guest opens the window】 When such a life suddenly becomes unbearable and you open the second-floor window, that is the end. You will inhale the cold air directly, and your right hand, your lungs, and your heart will freeze.

<Supplement> There is still plenty of food.
