There is someone

There is someone walking behind you,
turn around, look at me.
There is someone watching your footsteps,
turn around, look at me
There is someone who really needs you,
here's my heart in my hand.
Turn around, (turn around,) look at me,
(look at me,) understand,understand,
That there's someone who'll stand beside you.
Turn around, look at me.
