K.
That was the best description Laura could ever tell K about her father's physical appearance.
K thought that was probably the reason why she loved listening to Cat Stevens' songs so much growing up. It provided her so much solace, and a feeling of belongingness, whenever she played his songs - especially his track Moonshadow. In her pre-teen years, she even kept on fooling herself that he was indeed her dad, and that he had to go and leave them because he's a superstar.
