after the quest, I'm going to the statue of marriage and I can take the two quest for marrying the girl. After I forged the 2 ring, I talk to the nun, and scene of marriage of Elly stated, after this marriage, I talk to the nun and the marriage of Ryoko started. This is what happening. So the problem is in nun, takey priority to Elly and not to Ryoko? (Sorry for my English -_-')
