Sasurai no Taiyou

At a hospital, two girls are born into vastly different circumstances—one to a wealthy family and the other to a poor one in the city's slums. A nurse named Michiko, acting on a personal vendetta, swaps the infants, altering their destinies. As they grow up, their lives remain connected, with the affluent Miki mistreating the impoverished Nozomi. Despite their differing backgrounds and treatment, both girls share a common aspiration to become singers.
