Short poems in romances were regulated by the style of narration and had their own meanings. It would not be effective to understand them totally as "Poetic Stories", and they were not merely means of communication in Heian Era. Mental status of characters in some chapters of The Tale of Genji and The Tale of Ise were described only by short poems. They looked like primitive emotional songs in ancient folklore, compared with modern "Poetic Stories" which had a function of communication. Unexpectedly the relation between poems and narration in Genji and Ise was not modern but ancient.
