love & Rosalina of course...The chords are fine :)

        F
You went to live your life
       Am
But why'd you have to go?
G
You're my only hope
                           F
My only never ending hope
       C
Firefighter
        G

You took my heart away
         Am
And now I miss you so
G
You're my only hope
                           F
My only never ending hope
        C
