The Hardware Store Behind My Wall Saves a Kingdom

Mina Lane runs a failing corner hardware store. Late one night, Kael, a wounded stranger, stumbles in asking for a candle — and unwittingly reveals a hidden portal in her storage room leading to another world. As commander of the border fortress Ironwall Keep, Kael is trapped under siege with all fire oil exhausted. Using only ordinary modern tools like flashlights, walkie-talkies and drones, Mina turns the tide through supply management and practical ingenuity, saving the fortress and reviving her shop. A slow, steady bond grows between them amid cross-world perils.
