There hasn't been a lot of info about the plot, actually. What I have read around is that the mini series depicts teachers lives/way to teach in different moments of Japan History. Sho's is the first episode and the time setting is after WWII. I am not sure if his character was a teacher before the war or a student, but after the war, where he lost an arm (;_;) he comes back to teach and it's is supposed that he is still in a wartime like mind frame. The AKB girl is another teacher (English teacher I think) that sees things differently as he does. And there is also his sister in law (I suppose the brother died in the war or something) so it is supposed to be something like a love triangle...

I hope I am wrong in my assumptions and we get at least a kiss... it's not too much to ask no? but knowing Sho's luck in romance in his previous dramas... *cough*

I actually hope to know more about it soon. I am kind of obsessed with this drama. I like to think that it was Sho's personal decision do to this drama... You know how he cares about studies, Japan history and reality... I don't know, and knowing he lost weight for this (hope Jun invites him to a banquet or something when the filming finishes) it looks to me like he has invested a lot effort on this -no that he didn't do it with his previous works- but it looks like something that really matters to him... like that docu drama about the Kobe earthquake... Don't really know if this makes sense :S
