Could mean anything really its quite open to interpretation i think it could be about a girl who is seeing a guy but its all very secretive maybe even just sexual when they first meet thats why shes his goodnight girl cos they only really see eachother at night and nobody knows and hes not telling anyone. Then he falls for her and gets caught up in her world wanting the love he feels when they are together to be all the time he thinks/hopes she feels it too "reflected in your eyes". could be totally off the mark with this meaning though!!
