There is an interview with the writers where they claim that they didnt include any "i love you" scene because they thought the viewers would find it an insult to their intelligence (as in "No duhh! Tell me something i dont know")
The series has been going for quite a while, but the anime has got only 2 episodes out before this first pic here. Still no match for Machikado Mazoku, which got its first here barely a day after first ep :))
