No bro, I'm upset that (some) readers of this manga aren't capable to express more sentiments than hate or love for the characters. You know, I don't particularly love or hate anyone in this story, because they are all, more or less, equallly flawed. Yes, even Torago is full of flaws after all. Not that she deserved to be punished so harshly, but she was punished by the old hag KUUROO, which is basically the law on the island, not by Maname or Kukuri or Momoe. You can hate those characters as much as you want, but the truth is that in a similar situation you would have done the same things they did. It's because people are selfish, that can't be helped. If you think you would have done something different...well, you are a bunch of fools.
And now it would be interesting if you aswered to me saying something meaningful, just for one time.
AND BIG SPOILER
dear stilgar, you will despise the ending of this manga, since Maname survives...
But also many villagers don't even believe the island is going to shit, because they believe what the old Kuuroo said...She said there's no need to leave the island, so for many of them there's no need to build a boat either. There's no much time left of course, considering all that happened so far, but also there aren't enough people to help build the boat(s).
