classic waka stream

From Suma’s shore
The smoke where the fisherfolk
Burn salt for their trade—
The wind blows harshly upon it,
Drifting where it never meant.

Meaning
On the shore of Suma, the smoke from the fisherfolk burning salt is driven by the strong wind and drifts away in a direction it never intended.
Commentary
112. The Fisherfolk of Suma

There was a certain man. He had a woman with whom he had made a sincere promise to become husband and wife, but she turned her heart toward another man.
The poem was composed by the man.

In the poem, the smoke represents the woman, and the wind represents the other man.
Perhaps the other man’s temptation was very strong, or perhaps the woman had circumstances she could not avoid. If she yielded to temptation, it can be said that the woman was unfaithful.
