Season 2 of Good Morning Call pushed the story one step further.  I waited for this after being enthralled by Season 1.  I would love to have a season 3 9AND 4, AND 5 , AND 6...) - and I would also love to see Issei (Ramen guy) back.  The challenge will be to the writers.  The think tank group for the series will be challenged in  developing the characters of Natsume (what a handsome guy), Daichi, Issei, Marina, Mitsuishi, Abe - as they all grow up together.  It will certainly speak to an international audience about the millenial generation and how they negotiate relationships in the process of growing up.  It is so refreshing to watch a series that focuses on the reality of teenage life with all the confusion that goes with it.
Good Morning Call is, thus far, my favourite Asian drama.  It is bittersweet, funny, romantic, and best of all - not a dark teenage series (so unlike hollywood or American TV series which reflects dark recesses of the soul).  Congratulations!  Please, please keep Good Morning Call alive.
