Karkat has always had a bit of a problem with being nice to others. That's why he doesn't stay in relationships for too long. They come and go, just because he doesn't kniw how to control his anger. Then came Dave. He understood Karkat's anger issues, even so a bit more than Karkat did himself. The two grow to be close friends and develop feelings for one another. Yet, both are too nervous for their own good.
