Modern man Ethan is unexpectedly transported to the Viking Age and, upon waking, is forced into an arranged marriage — saddled with an absurd system: three target wives, and if he marries fewer, he's erased! Gentle Liv, fierce shieldmaiden Astrid, and shrewd merchant widow Ingrid each guard their hearts and hide their own secrets. Raising their affection earns modern supplies — from hot food to firearms that crush cold steel — and Ethan wins the women's trust while fending off the powerful men who covet them. From a shabby hut to a farm outside town, can he carve out his own territory in this chaotic age with his system and his three wives?
