After dying in Japan, a young woman is reincarnated with her memories intact—only to be abandoned as a baby at just five months old, left to freeze under a wintry sky.

Luckily, she’s found by the kind (but struggling) couple Joe and Marissa, who run a failing inn and tavern called The Cat Under the Tree. They take her in, giving her a second chance at life.

But this isn’t the cushy fantasy world she might’ve hoped for—her new home is dusty, the food is bland, and survival as a commoner isn’t easy. Determined to repay their kindness, little Millie—armed with adult knowledge in a toddler’s body—sets out to help turn things around.
