In this drama, Ma Dong Chan, a renowned producer in the entertainment industry, and Go Mi Ran, a part-timer struggling with family debts, become participants in the "24-Hour Frozen Human Project." This experiment was supposed to freeze them for a day but instead keeps them frozen for two decades. To survive, they must maintain a body temperature below 33°C. As they thaw, they face unresolved personal challenges while adapting to a world that has moved on without them, all while trying to repay their family's debts. (Source: MyDramaList)
