Grusha sighed reluctantly and put his hands into the pockets of his coat after giving you permission to use the ski slope...

You had a lot of fun sliding down that snowy hill, although walking back up was a drag.

However, you noticed someone standing on top of the hill once you hiked up again...

Once you noticed him, Grusha averted his gaze - acting uninterested yet it was obvious that he had been observing you.
