Baby & Me

Takuya is a normal Japanese elementary student whose mother died not very long ago, leaving him alone with his father and his baby brother Minoru. But his father is a busy man, and Takuya has to look after Minoru. Because of this responsibility that would normally never burden a child of his age, Takuya sometimes resents his fate and his baby brother... but his love for Minoru gives him the strength to carry on.
