So, I recently watched a Japanese Drama called Attention Please.

I absolutely loved it! It's about this really "rough" kind of unfeminine girl who takes a joke said by her crush a little too seriously and decides to become a "Cabin Attendent".

Does any one know if there is a manga that it's based upon?

I was briefly looking around for you, and wikipedia says that a manga does exist but i couldnt find it online. which leads me to believe that it hasnt been scanned/translated yet. u.u sorry to disappoint you.
