Zen remembered that he was feeling so emotional at the moment Anastasia awakened that he ended up appearing like some sort of a bad guy to her.
At first, he was only standing in the dark, silently observing her all the while. That time, she was not able to notice him there. He did think it was better that she did not, though.
After all, Zen could imagine his expression as soon as he saw Anastasia - with his eyes turning all starry and dreamy, his cheeks blushing from how endeared he was by her beauty, and his overall demeanor coming out to be somewhat staggering from all these emotions.
He felt like dreaming during that fraction of time. Then again, he had waited four long years for this moment. They were years that were full of sleepless nights, endless worries, everlasting struggles, and an incredibly tremendous amount of hard work.
Above all, they were years that had him longing for her to wake up like this - to see her moving at last.
