Except it's not. The competitiveness in KareKano was one sided on Yukino's part and she KNEW that Arima had a crush on her and was planning to break his heart so she can be number #1 in her school so she can be praised over it. Plus it pretty much ended around the 2nd volume.
Hikari only wants to be number #1 only to beat Kei and nothing more. Plus her cluelessness about Kei stems more from never suspecting that her childhood rival likes her, never minding liking her in that way. And I LOLed people think the setting is stupid when it's pretty similar to Ouran (AND NOTE, Special predates Ouran).>>11076576
