Regardless of my feelings on Kim/Ron, I think the show could've done a better job of portraying them as having feelings for each other.
In "Grudge Match" Kim mocks and insults Ron for even suggesting that people might think they date. This does not indicate that she's secretly crushing on him.
In "Emotion Sickness" Ron is uncomfortable with the idea of dating Kim. This does not indicate that he's secretly crushing on her.
In "Bad Boy" Kim suggests Ron take a date to Rueben's wedding, but gets uncomfortable when he asks her to go. They both agree that it's not a "date-date".
(I will give them props, Kim and Ron's conversation about the main characters of Agony County getting together was a nice lampshade.)
I will admit that Kim was jealous of Yori in "Gorilla Fist", and her conversation with Ron about Yori crushing on him could be a nice parallel to Kim's situation.
However, Kim was also jealous of Felix in "Steal Wheels", so it's not like she has to consider someone to be romantic rival to be jealous of them.
Ron is never shown to have issues with Kim dating, even attempting to help Kim with Josh.
And, though she doesn't seem to think highly of Ron, she doesn't have a problem with Ron dating.
Before "So The Drama" there wasn't a lot to indicate that they were attracted to each other.
Actually, there was more to indicate that they only see each other as friends than that they were secretly attracted to each other.
In "So The Drama" we get a lot of Ron pining over Kim, but only one line near the beginning that might indicate Kim is also pining over Ron.
And then, there's Eric.
Eric was perfect for Kim, and she begins to ignore Ron because of him.
This prompts Ron to realize his feelings for Kim, but he doesn't act on them until after Eric is revealed to be part of Drakken's plan.
Which is another problem; Eric was part of Drakken's plan.
Aside from one line at the beginning, there wasn't much to indicate that Kim was crushing on Ron. So having her date him after it's revealed that Eric was part of Drakken's plan makes it seem like Ron's the rebound.
Honestly, having two people end up together because the alternate love interest was no longer an option is kind of lazy writing.
(Granted, they hadn't been expecting the show to continue after this, so I'm not too surprised.)
Still, Kim ended up with Ron not because he was the better option but because he was the only option.
And that's just unfair to both of them.
