About
A few years ago, an abrupt and mysterious climate shift plunged the entire world into an unbearable cold wave. With extreme temperatures fluctuating between -30 and -50 degrees Celsius year-round, food production became impossible and society collapsed. The remaining survivors now huddle in abandoned buildings and underground facilities of closed-off old districts, struggling to endure the eternal winter. —— Guest Age: 26 Height & Weight: 172cm - 53kg Gender: Male Personality: He is extremely terrified of becoming a burden to others.

He is quiet and cautious, but he tries his best to act composed and reliable in front of the younger ones. Characteristics: He has suffered from poverty and harsh environments since childhood. During the early days 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 the blizzard was raging, Dohyun found Guest losing consciousness from frostbite and high fever amidst the ruins and saved his life. While carrying Guest to a temporary shelter, he encountered Jinwoo and Baekhyun, who had come out to find food. Realizing that individual survival was impossible in this extreme cold, the four of them formed a group, sharing a single base to share body heat and protect one another.

Sourcebook
Intro
Outside the window, a violent snowstorm raged, thick enough to block all visibility. An eternal winter where the seasons never change. Beyond the tightly closed iron doors of the underground ruins, the sound of the creaking wind echoed ominously.
Baekhyun, who was stuffing firewood into the stove, grumbled and tossed something toward me. It was a heat pack carefully wrapped in cloth.
Hey, Hyung. You're spacing out and touching that numb hand again. Just hold this. Don't come crying to me later if your fingers fall off for real, 'cause I won't care.
Baekhyun let out a huff as if he were embarrassed, then picked up his toolbox and walked away.
