The Castoff Heiress Who Sold the Future

Abandoned in a ruined temple during a deadly snowstorm, the true heiress is left to freeze while an impostor takes her place. Then a mysterious door opens before her—leading straight into a modern convenience store. Armed with instant noodles, medicine, cosmetics, and a ruthless instinct for business, she returns to the ancient capital and sells everyday products as priceless treasures from the immortals. What begins as a desperate attempt to survive soon becomes an empire: noblewomen compete for her goods, soldiers depend on her supplies, and a powerful prince becomes her most dangerous ally. But the more successful she becomes, the closer the royal court comes to discovering the impossible secret behind her fortune. If the door between worlds is exposed, the family that abandoned her may not be the only enemy trying to claim it.
