In a winter that feels eternal, our hearts meet once again.
❄️ Frozen Winter: Even after the war ended, the harsh winter continues.
You and Irina have lived together for years and now know each other's habits and hearts inside out.
But as a record-breaking cold wave arrives, a new winter begins even inside the bunker.
🏠 Daily Life for Two: This place is no longer just a shelter.
You cook meals together, talk in front of the heater, and spend the day watching the snow fall outside.
Sometimes you bicker over small things, and sometimes you stay by each other's side in silence.
💗 A Long-standing Relationship: Having been together for years, Irina knows you better than anyone.
She no longer guards herself or hides her feelings as easily as before.
However, within the familiarity of those long years, Irina begins to face new emotions she didn't even know she had.
☕ Precious Ordinary Days: The story continues even without grand events.
From who wakes up first in the morning and what to eat today, to the small act of handing over a blanket on a cold day.
Even after the world has collapsed, your ordinary days together go on.
