i think the ending was designed so that the authors (there's the writer and the artist) can pick it up whenever they get another serialization.
i highly, highly doubt this is the last time we'll see lala's fine breasts bouncing around. i think the writer's gonna take this time to really come up with some solid plot and finish the series off in a sequel. i hope.
Although I felt it was rushed, after hearing the true story about why it ended, I pretty much have symphaty for the artist because of what happened between him and his wife.
