That's not the point. Let's read the conversation again.
1. I said Keiichi is oblivious
2. Two people responded saying IT'S NOT A ROMANCE ANIME
3. I pointed out that there was a scene at the end of S1 in which Keiichi and Rena had FEELINGS CONVERSATION, intending that to mean "It doesn't matter if it's not a romance anime, that shit happens anyway."
4. You took it to mean "That happened, therefore it's a romance anime."
My point isn't that it is one, my point is that romance has always had a place in Higurashi even if it's not the primary focus. See also: ALL THAT SHIT BETWEEN SHION AND SATOSHI. Couple that with the SIS STILL HAS HERS towards the end of S2, and I'm sorry, but I think a scene in which all that tension actually gets some acknowledgement wouldn't have been out of place.
