In the frostbitten expanse of Levantret, where the sun often hides, Lord Ritzhardt, known as Ritz, cherishes his homeland under the enchanting Northern Lights. Desiring a spouse, he faces rejection from those unready for rustic life. Branded the 'Yeti of the Borderlands' by elites, Ritz meets Sieglinde, a revered lady-knight, and impulsively proposes a year-long 'trial marriage.' For Sieg, a chance to explore domesticity after a military life unfolds, while Ritz aims to showcase his land's rustic charms, from frigid hunts to hearthside crafts, weaving a tapestry of newfound warmth.
