The original owner's family has a miserable fate, facing a forced marriage crisis right after time-traveling. Accidental awakening of an entire ocean and luxury yacht space, holding a seafood treasury. A family of three takes root in the Great Northern Wilderness farm, avoids the original tragedy, builds life relying on ocean supplies, and strives to live well in that era.
