A five-year-old with a past life's muscle memory becomes the only person holding a crumbling noble household together through cooking, sewing, and pure spite. The show lets him be genuinely competent without erasing how small and tired he actually is. By episode three you stop laughing at the premise and start watching a kid figure out how to raise his brother while aristocrats burn the world down around them.

Five-year-old Ageha suddenly recalls memories of an entirely different life. In his past existence, he was someone who found joy in cooking, sewing, and singing. Now the overweight only son of Count Kikunoi, with no allies and no useful skills, he learns that a younger brother named Regulus has suddenly entered his life, a boy who seems fated to kill him one day over the right to inherit. Corruption is spreading among the aristocracy, and the two brothers will need the skills from Ageha's past life to get by. Ageha ends up raising Regulus and becomes a doting older brother, making handmade educational toys and cooking him steamed egg custard. The same homemaking skills let him ease the hard lives of the people in his territory, and with magic and blessings from gods and elves, the young brothers set out to manage their land in a fantasy comedy about family and everyday life.
