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, motivated by a personal vendetta, swaps the infants, altering their destinies. As they grow up, the girls' lives remain connected. Miki, raised in privilege, mistreats Nozomi, who grew up in hardship. Despite their differing treatment, both share a common aspiration to become a singer.
