I'm a little confused about the seasons...

is the first season the whole manga? or is the manga broken up into the three seasons?
or is all the seasons that are out completely based on manga?
so confused..

I have only watched the first season..

Based on what i watched and read, it's not completely like the manga..

But the characters are based on the manga..

I like the story in the manga better..

The characters in Season 2 and 3 are different from the manga except for Yankumi and her family..

well, that's what I know..

I'm watching Gokusen 2 now..

I think that Gokusen 2 has many scenes that's just like the manga..

Like in the manga when Shin asked for a duel from Yankumi but this time it's Yabuki Hayato..

and when they were framed up..

While watching it, I remember the manga..

guess it's a bit different frm the manga.... every season, yankumi likes a new guy...and every season will have ppl graduating.
