Krystal blushed a little when Crocell picked her up. Is was slight and didn't last long, but one of them may have noticed it.
However, Krystal is quickly distracted by the view around her as she is taken down. It was a great view. The entire city around her. She didn't really look at it too much during the race.
Once on the ground standing, Krystal will give Crocell a quick hug. Thanks for that. It was fun.
Then she waits for Kin to catch up.
