That was my honest reaction when I've seen that a second season has started. Not that I ever wanted this manga to end, it was just me realizing, that we'll never ever get any closure, with this story.
When the original manga ended (I think it was almost summer), I thought, that it ended for good. I was a little sad that no one won the harem, but it was unlikely to begin with, and it seemed that any point is as good as any to end it.
Seeing only after half a year that the series had resumed was a big surprise. The setting and focus had a slight shift (it was about damn time), but nothing else really changed. I hope this season will be a bit different than the first, and will have a direction, rather than just a main theme, because I loved the perverted idyll of the first season, but frankly I'm a little tired of it, and I want to see something new!
With TV sitcoms, the change is inevitable, because actors grow older, regardless of the script. With manga it's possible, but where is the fun in that? Someone please pull out the "Drama" tag.
