A boy from 2020 wakes up in a future where humanity stopped existing and the only people left are a family living like it's the Stone Age. The comedy is pure culture shock, watching someone completely addicted to modern convenience get stripped of everything and actually have to participate in survival. Gen doesn't learn a lesson about simplicity or find peace in nature, he's just miserable and hungry, which is exactly what makes it funny.
Gen wakes up in a world that shouldn't exist. Pulled forward centuries by accident, he finds himself in a future where humans vanished long ago, and nature has reclaimed everything. The only comfort waiting for him is the Ganko family home, nestled deep in a forest that's grown wild and untamed. There's no electricity here. No internet, no convenience stores, no way to contact anyone from his time. Gen has to relearn how to survive without the technology that once felt essential, swapping his smartphone for basic necessities and his gaming habits for actual work. The Ganko family, odd and stubborn in their own ways, becomes his unlikely support system in this strange new reality. What begins as culture shock transforms into something stranger: Gen slowly discovers why humanity disappeared, and whether he's truly stranded or if there's a way back. Between learning to chop wood and questioning his survival instinct, he uncovers the mystery of this empty world one peculiar day at a time.
