I believe that everyone, in some way or another, has a second (or more) set of “parents”. This is a broad definition of parents I am using here – they may be people who cared for you when your biological parents were having problems, such as grandparents or aunts and uncles, or even godparents as is the custom in some places. They could be people who took you to the movies or to fancy restaurants if the money in your family was tight. They could be people close to you whom to others might seem commonplace but to you were heroes. They could be teachers, formally or not. The common characteristic among these people is that they were role models for you and had a big (positive) impact on your life in one or more ways.
I was lucky enough to have several such wonderful people in my life during childhood and adolescence, but one couple stands out.
