A couple of things

At first, Rye could have sworn that Klas was joking but seeing the seriousness on his face was shocking to her.  Considering the fact that she continued to sit on his bed. 

"We're only going to kiss until I'm done filling up my magic storage," Rye seriously told him, meaning every word. 

Klas on the other hand simply nodded his head and smiled as he moved closer to her.

"Kiss? and a couple of other things!"

"We're not going all the way!" Rye repeatedly was unable to fathom what else they could possibly do that would involve them being in close physical contact if it wasn't related to kissing.

Seconds later, Klas had indeed climbed back on the bed and this time around he had a more serious expression as he stared deep into her eyes.
