This song talks about the feeling of pure innocent love that we feel towards a special someone that most of us experienced growing up either as a child or a teenager.

Most of the time we keep it as a secret simply because of shyness, but it also can be the fear of what that special person might think of us if they knew about our feelings towards them, hence the title
“Top Secret”.

In the last parts of the song, it hints about slowly but surely getting the courage to finally reveal the secret that we are keeping to ourselves. Ultimately teaching us not to let our fear or shyness get the best of us, so that we can express our feelings openly and not keep them as just a secret.
