the cares of love begin.

Headnote: "Sent upon hearing, around the Third Month, that another man was visiting and sending letters to someone with whom I had been exchanging words"
This poem was sent around the Third Month upon hearing that another man was also visiting and sending letters to a woman with whom the poet had been exchanging words. He says that since he set his heart, which is not dew, upon the blossoms, each time the wind blows he worries that they will scatter. The blossoms stand for the woman and the wind for the other man courting her, expressing anxiety that her heart may change. The poem is skillfully built on a chain of related words: dew, settling, blossoms, and wind.
Ki no Tsurayuki was a poet of the early Heian period, the son of Ki no Mochiyuki. He was the leading compiler of the Kokinshū and wrote its Japanese preface. He served as Governor of Tosa and is also known as the author of the Tosa Diary. He is one of the Thirty-Six Poetic Immortals.

First line, "tsuyu naranu": "not dew." Since dew settles on flowers, he likens his heart to dew while saying it is unlike fleeting dew.
Second line, "kokoro o hana ni": hana, the blossoms, stands for the beloved woman. Following the cherry blossoms of the previous poem, 588, here too the beloved is likened to flowers.
Third line, "okisomete": oku is an associated word of dew, overlaying giving one's heart with dew settling. Somu means to begin to do.
Fourth line, "kaze fuku goto ni": the wind scatters blossoms and stands for the other man courting her.
Fifth line, "monoomoi zo tsuku": monoomoi is the brooding of love, and tsuku means to arise or be added. The binding particle zo is resolved by the attributive tsuku.
