"Two Seasons: Summer - Autumn 2019"

During a normal simultaneous turn, I benefited, but the opponent didn't acknowledge it and even refused a draw. I conceded.
However, in this game, it was still a normal simultaneous turn. I decided to move through a passage to the opponent's area and proactively requested to stop the simultaneous turn, but after seeing me approach, the opponent immediately demanded that the game not be counted. I think this is unreasonable. Moreover, in this game, the opponent had absolutely no chance of winning.
The opponent can appeal to the referee.
