Looking for drama where the girl is one of those shallow, superficial, rich girls who basically only cares about designer clothes and her image/status who meets a guy who slowly punches through her shell and she transforms into a normal warm girl with a heart. If you get what I mean... 

Was a while since I saw it, but iirc You Who Came from the Stars had this.
