Ryuko and Mako: Kiss once, promise to go on a date together, go on said date together
KLK Shippers: That's OBVIOUSLY a platonic relationship. Just because they smooched once doesn't mean they're in a relationship. Besides, we're obsessed with Mako getting together with Gamagoori because it makes for better porn.
Ryuko and Nui: Kiss once, while Ryuko is being mind controlled, dealing with severe emotional turmoil, and they hate each other's guts throughout the whole show
KLK Shippers: Now THAT'S a romantic relationship! 
Me: 😒
