異世界往来: 饅頭ひとつで嫁をもらう

Stranded in a famine-ravaged era, Conrad Hayes unlocks the Two-Way Gate System—a bridge between eras powered by marital bliss. His first wife, the ailing Joyce Bennett, is bought with a single steamed bun. Soon, he rescues her sister Sherry and shelters the poor girl, Renee. Using the Gate to trade across time, Conrad amasses wealth and influence, but danger follows every move.
