TV movie 2000s

Hello !!
I’m looking for the name of a TV movie I really liked, it was on TV in the 2005s-2010s but I can’t find it on the internet. Here is all I remember about the plot. The story was about two teenage girls who dislike each other. They have a fight at school. One of them was blond and rich, the other had black hair and was poor, they had to swap houses. The parents of the black-haired girl had a shop, she ends up with the blonde’s brother. End of the story, I cannot recall any name, year, director.

Thank you for your help.
