Drinking wine together. Betroth Jiraiya Tsunade's wine into a bowl. Just look at the picture on the bottom right corner, visible Jiraiya and Tsunade being hugged. Hohohooww ... whether this is a scandal, or indeed there is love between them. But if you saw the words "ai" meaning love in the top left, maybe the makers of this picture makes no love between the two Sennin, ie Jiraiya and Tsunade.
