Answer: When it's a response to an incendiary review left by an anonymous reviewer who seems to be too cowardly to let me respond to them privately.

"This is so stupid. So Kurt doesn't want to kiss or do it with Blaine so Blaine assumes that Kurt doesn't love him? Yeah, this was pathetic."

Yep. That's it. That's exactly what happened in the fic.

I apologise for doing this, I will take more consideration for the brain-dead monkeys who have no reading comprehension skills at all the next time I write a fan fiction online, and not make plots more complicated than "Blaine loved Kurt and then they kissed and that was the end". I do apologise.
