Attention Please

Since her childhood Youko Misaki was kind of tomboyish girl, she never liked the stuff other girls did, so she joined some boys to play with them. After her friends go apart for work, she has the idea of becoming flight attendant.
To reach her goal, she moves to Tokyo and undergoes a qualifying examination, in which she does not seem to do so well. She gets accepted anyway and has to do the training, which seems boring to her because she thinks the theory is not that important in the job. And so she does not act very professional when her instructor gives her an assignment, but in the end she mostly solves it...
