Just considering the title "Rooting for you" I expect the song to tell about unrequited love. 
But the singer hopes to be able to conquer the woman he is in love with.

The song consists of two verses and two alternating choruses. 
The first verse is composed of seven lines while the 
second verse of five lines. the refrains have, instead, nine lines.

In the song there are no rhymes and sad words are used because the singer is sad because he doesn't have the persna next
to him that he wants.

In my opinion, the message of the work is not to give up and the courage that a person can have in feeling alone.
In my opinion this song is a way to describe one's feelings and emotions.
