Roma-ji: Madoromade hitoyo nagameshi tsuki miredo okinagara shimo akashigao naru
English Translation: Without a moment's sleep
I gazed all night at the moon,
yet you, it seems, wear
the frost-white face of one who
kept awake until the dawn
Meaning: I watched the moon all night without a moment's sleep, yet you put on the face of one who stayed awake until dawn.
Commentary: 27 Frosty Mornings and the Page Boy

On the night of their exchange about the arm-pillow sleeve, the moon also shone very bright and clear, and Izumi Shikibu and the prince each gazed at it until dawn in their separate places. The next morning the prince was having someone ask whether his usual page boy had come, meaning to send a letter. Meanwhile Izumi Shikibu, perhaps moved by the brilliant whiteness of the frost, sent a poem first. The prince was vexed at having been forestalled.
The woman is Izumi Shikibu, daughter of Ōe no Masamune and, as the wife of Tachibana no Michisada, Governor of Izumi, mother of Koshikibu no Naishi. The Prince of the Dazaifu is Prince Atsumichi, fourth son of Emperor Reizei, so called because he served as Governor-General of the Dazaifu. The page boy was the youth who carried the prince's letters to her.
The prince's letter brought by the boy contained "Nenuru yo no tsuki wa miru ya to kesa wa shimo okiite matedo tou hito mo nashi." Seeing that the prince had indeed written first, Izumi Shikibu was charmed that they had been of one mind, and sent back this poem.
Amused that the boy seemed to fear how badly he would be scolded, she wrote "Shimo no ue ni asahi sasu meri ima wa haya uchitokenikeru keshiki misenan" in the margin, adding, "The boy seems quite crestfallen."

The first three lines mean "though I watched the moon I gazed at all night without dozing," answering his "whether you saw the moon" by saying that she herself had watched it all night, with a past-tense auxiliary and an adversative particle.
The lower verses mean "you wear the face of one who stayed up till dawn," where "shimo," as in his poem, is an intensifier that also means frost, and "oki" echoes frost settling. To his claim that he was the one waiting, she retorts, using his own wordplay, that she was rather the one who stayed up all night, in a light and lively exchange.
