Drawn by agreement

I came across the game below, and it was drawn by agreement. Can anybody figure out why?

Might be a bit more believable if White was in time pressure and the stake wasn't a prime next-round pairing, but rather a prize.  Although, in that case, there's little reason for White to stop early.  Unless this game was from before they instituted the draw-on-time rules.

White was inexperienced and his opponent tricked him into shaking his hand (draw), or fooled him into believing that because he moved his king between g5 and h4 three times it was a draw by repetition. Both events have happened before.

It wasn't time or tournament, this was a chess.com game

White and black were good friends, the game didn't mean anything, and black jokingly offered a draw not expecting white to accept. I know it's possible because a similar scenario happened with me as the "white" pieces.
