It also creates angel beats! season 2 ? I want to know ..

For a few days I started to watch an animê called : AngelBeats!
and of course I finished . The thing is that the last episode I created a feeling of sadness that I have and still today: / . I looked , and it contained a segundo season or season 2. I want to know whether even longer and the season starts in February , still want to know what happened ..
Damn .. Best animê ever released ..
