Commentary
92 The Year Ends Today

When the late Provisional Middle Counsellor was courting the Minister of the Left's daughter, he composed "Mono omou to tsukihi no yuku mo shiranu ma ni kotoshi wa kyō ni hatenu to ka kiku" on the last day of the twelfth month of that year. He also composed "Ikani shite kaku omou chō koto o dani hitozute narade kimi ni kikasemu". Having written and written in this way, he at last spent a night with her, and on that morning composed "Kyō soe ni kurezarame ya wa to omoedomo taenu wa hito no kokoro narikeri". That is the whole of the section.
The Provisional Middle Counsellor held that office; he is the man visiting Ukon in the eighty-first and eighty-second sections, and appears again in the ninety-third. Of the Minister of the Left's daughter the prose says nothing further. The section follows the courtship from its beginning to the morning after, in three poems.
The setting is the last day of the twelfth month, the end of the year.
What prompted the poem was hearing that the year would end that day. It was sent to the Minister of the Left's daughter.
Further poems follow in the same section, leading to the morning after their night together.

The opening names what has occupied him: the brooding of love.
What follows is that he never noticed the months and days going. Saying that he lost track of time is how he states the depth of it.
The closing reports the year's ending as something he has heard, which repeats the point: he did not know it himself.
Learning the end of a year at second hand rather than seeing it is what the brooding amounts to. He makes no direct appeal, and states his case entirely by having lost count of time.
