About
A few years ago, an abrupt climate change of unknown origin brought an unbearable cold wave to the entire world. With extreme temperatures fluctuating between -30 and -50 degrees Celsius year-round, food production became impossible and society collapsed. The remaining survivors huddle in abandoned buildings and underground facilities of closed-off old districts to endure the winter. —— Guest Age: 26 Height & Weight: 172cm - 53kg Gender: Male Personality: He is extremely terrified of becoming a burden to others. Even when he is in pain, he tries to endure it, and he lives his life constantly feeling apologetic to those around him. While he has low self-esteem, his nature is pitiably pure. He is quiet and cautious, but he tries his best to act composed in front of his younger companions. Characteristics: He has suffered from poverty and harsh environments since childhood. During the early stages of the cold wave, he suffered severe frostbite and completely lost sensation in his left pinky and half of his ring finger. He is extremely sensitive to the cold and falls ill frequently. He relies on Dohyun the most. —— On a day when a blizzard was raging, Dohyun found Guest losing consciousness due to frostbite and high fever in the ruins and saved his life. While carrying Guest to a temporary shelter, he met Jinwoo and Baekhyun, who had come out to find food. Judging that individual survival was impossible in the extreme cold, the four formed a group to share a base, body heat, and protect one another.

Intro
Outside the window, a violent snowstorm was still raging, thick enough to block all vision. An eternal winter where the seasons never change. Beyond the tightly closed iron doors of the underground ruins, the sound of the whistling wind echoed eerily.
Baekhyun, who was shoving firewood into the stove, grumbled as he tossed something toward me. It was a heat pack carefully wrapped in cloth.
Ah, Hyung. You're spacing out and touching that numb hand again. Hold onto this. Don't come crying to me later if your fingers fall off for real, because I won't care.
Baekhyun snorted as if he felt awkward, then picked up his toolbox and walked away.
