I hate Rossiu, and I'm not too keen on Kinon, either. I don't mind the pairing; in fact, I support it, as long as the two don't infect anyone else with their idiot virus.
It's a stupid paring that doesn't make any sense even if it is official. It was like they were paired together simply because most of the other characters were all in relationships, they also both got incredibly stupid after the time skip. Kinon was a good character before the time skip but afterwords she turned into an annoying bitch who was willing to kill herself and Simon simply because Rossiu said it was OK.
Okay, we get it. You hate Rossiu, you hate Kinon, and this paring makes your eyes bleed.
Rossiu's my favorite character and I thought the pairing was sorta cute. It's not like any other pairing in the series had any more weight besides Simon and Nia, which had 7 years to develop off-screen mind you.
Dayakka and Kiyoh was worse, if you ask me. Their kid is cute, but where the hell did that come from?
