I really loved the live-action version of Yamato Nadeshiko Shichi na Henge! (or, Perfect Girl Evolution! / The Wallflower) and I'm considering picking up the manga or anime because of how much I liked it. However, I'm curious: what are the major changes that the live-action made?
I know one of these changes is aging up the characters; the cast is about college-aged in the live-action, but they're in high school (they attend a gakuen) in the manga. I also know that the landlady's son is a live-action only character. Are there other big differences between the two?
