Jinno Sakurako was a very poor child in her past. She lived with her poor family in a small village and was really unhappy with her life. Therefore, she ran from home with the money, making a changeover into a beautiful woman that everyone will like and starting to work as a stewardess. She believes this will be the perfect place to find her one and only rich man that will be able to please her.
Those two are different; they have two different subjects and different roles. But at the same time, the main female character, who is also played by the same actress, remains the same. She might be poor in yamato nadeshiko, and in bijo ka yajuu might be rich and spoiled, but in the two dramas she makes a huge emotional progress in her point of view.
Both dramas are really good and enjoyable to watch, even comical at times.
