Does this mean...

Though She had relaxed a little, Zero Three's whole body went stiff the moment Sam's lips touched hers.

He kept it short, of course. Knowing it was her first, he wanted to be careful not to overwhelm her right away so he stepped backed and observed her reaction.

Three seemed to be a little shocked. She slowly raised her right hand a touched her thin cherry lips, a few seconds later her eyes began to sparkle as her aura changed quite a bit.

Noticing that Sam was watching her with a smile the young Valkyrie blushed once more. Not saying a word Sam went in and took another kiss, this time lasting far longer than the first. 

'Does this mean… that he likes me…?' Three Thought as the strange feeling in her chest continued to grow. 

She had never seen herself doing something like this for all the time she had been around, especially not with the man they referred to by Doctor.
