Desire was excited to see the first ever human that he would meet.
That was why he had such an expectant look on his face as he spoke to Jarina.
"Is that them?"
Jarina was worried about Desire if ever his emotions would get out of control, but she soon shook her head at that thought.
'He trained for this...'
Jarina is the person who was there for Desire when Desire was training himself.
She is also the one who suggested Desire practice the Cold-Blooded Trait.
That was why it was wrong for Jarina to doubt Desire at this point.
Although she knew how hard it is for one to keep control, Jarina wanted to see for herself.
Jarina wanted to see the moment when Desire wouldn't fuss over something like a human.
Either way, the result would come up naturally as the duo emerged from the trees and arrived at a place where there were no trees.
