SHIROHIYO - Reincarnated as a Neglected Noble: Raising My Baby Brother with Memories from My Past Life - S01

In a world where Western and Asian cultures mix, Ageha is the only son of Count Kikunoi of the Kiryuu Empire. His life was already over by the time he was 5. Born in a corner of the country, he has no allies or useful skills, and he is overweight. On top of that, his brother Regulus, who suddenly appeared in his life and was presented to the Count as his brother, will apparently kill him in the future for the right to succeed. His only weapons are the "cooking and sewing" abilities he suddenly gained along with the memories of his previous life in Japan. In the middle of all this, Ageha ends up raising his younger brother, but... "My brother is super cute?" And before he knows it, he becomes a full-blown doting older brother. Making handmade educational toys for his cute little brother and delicious chawanmushi (steamed egg custard)... With the help of his previous life's skills and his power as a housekeeper, he is able to improve the rough life of the people living in his territory. A fantasy of two young brothers managing their territory, where a single step gets even the gods involved in changing their country.
