This is Pansy and Blaise from the Harry Potter series. The way I see it, their families have been friends for years. One day, they think how adorable it would be to dress up the girls and have a portrait taken. Pansy thinks this is a great idea (woo! pretty dress!) whilst Blaise isn't quite so thrilled.
ETA: YES, Blaise is a boy. I know. Thank you. We've all read HBP, sugar plums. If that's really all you've got to say, spare me please. Or leave an e-mail address so my scathing response gets mailed to you. Makes my day, that.
