Comment by I need sleep. on Jinx - Chapter 48

Do they not do it" anymore before the day of the match? I thought this all started because of his "jinx" I don't know if they do it off screen or something but since they probably went to sleep sad/angry they most likely didn't do it. and the reason he tied maybe could still connected to the jinx but I don't think so. Can someone reassure me about this??
