Kaworu likes Paul's imperfections. He likes the rougher edges that Paul doesn't let a lot of people see. There's moments when he's clumsy, flummoxed, or even just dragged down by the dregs of sleepiness early in the morning. These traits are so endearingly human.

The first kiss makes him start to giggle, ribcage reverberating with a soft sound that is interrupted as the second kiss is pressed to his lips. He doesn't really mind their sour breath, though he's suddenly aware of how chapped his lips are and how dry his mouth is and how movement sometimes creates a stabbing sensation in his head.

Kaworu continues anyway. He slides a leg out from under Paul's and then kicks it over the taller boy's thighs, claiming his territory in the process.
