I can see where you're getting at. Well, it all boils down to personal preference yet again. I do agree that KnT is good at what it does, but it has its flaws too. What I was really bugged about was the excessive drama, and yet... I always fall for the drama that it shows. While I do think that the supposed 'ending' it had in season 1 wasn't a proper end to the budding romance between the two, I must say that it was a nice end to a season. If KnT was already scheduled to have a season 2 before the first season ended, then I can fully say that I was satisfied with where season 1 left us. But then again, if it ended on that note without any signs of a possible season 2 in the past, I might've raged. Such potential romance in a relationship, and yet...! They're too shy. That's all I can say. I guess they're what you call 'torpe' in the Philippines. Sadly, I do not know of a proper translation of the word into English. It means someone who isn't brave enough to portray their feelings, or someone that's afraid of the consequences of admitting their feelings. You get the point.
Still though. Cute set of characters, cute interaction, heartwarming anime. I loved it. I hope season 2 isn't shit.
