Even though the plots are different from each other, the main concept of a girl trying to change into something better is what links them together. In Skip Beat! the main character is going through a change of look/career/life out of revenge, while in Yamato Nadeshiko Shichi Henge, she is being transformed into a lady for the her own sake. Both dramas are funny, with romance aspirations and with moments that will make you "awwwwww". Not to mention the actors are really skilled. I really recommend both of them.
