Lyric discussion by BehindTheShadow 

To me its about a guy and he's just in love with this girl. But she spends her time hidden away hesitant to give into him and admit how she feels. He struggles to coax her out her shell and accept him. He wants her to break into the light with him. But at the same time he doesn't want to hurt her perhaps the title of "little sister" is to help him keep distance from her while trying to help her.

You whisper secrets in my ear(Her slowly breaking down and speaking with him) Slowly dancing cheek to cheek(Being intimate with one another) It's such a sweet thing when you open up, baby(When she does speak to him its the sweetest thing to him) They say I'll only do you wrong(Everyone around them sees him as a corrupter and doesn't want the two involved) We come together cause I understand Just who you really are, baby(Really self explanatory.)

Those are just my thoughts on the matter.
