Ten-year-old Takuya has a new job: to look after his baby brother Minoru…looks like it's time to put on the kid gloves!

Young Takuya has it tough. Since his mother passed away, he's had to take care of his baby brother Minoru while their father works the long hours of a Japanese "salaryman."

Takuya's life isn't limited to taking care of Minoru. He's got some problems of his own, like encounters with schoolyard bullies, a girl with a big crush on him, and the jealous classmate who has a crush on her. He weathers these challenges pretty well, but once they pose any kind of threat to Minoru...watch out!

Minoru also has a new admirer named Ichika, and the nursery school is rocked by the bitter rivalry that develops between her and his previous suitor, Hiro. How much will little Minoru put up with?
