Thank you, but I think you got this part wrong. K isn't the woman. K is Sensei's (male) best friend. Sensei invites K to live in the same guesthouse owned by the woman's mother. Sensei and K both fall in love with the woman, but Sensei doesn't have the courage to express his feelings to her. When K one day confesses to Sensei that he plans to propose to the woman, Sensei panics, pretends to be sick so he can stay behind with the woman one day, and proposes before K has the chance to. When K finds out that the woman and her mother have accepted Sensei's proposal, he (presumably wounded by both grief and Sensei's betrayal -- though he never says this, not even in his dying letter) withdraws into silence, and one day ends up killing himself.
Sensei and the woman end up getting married (the woman is Sensei's wife who the young man protagonist meets early on in the book).
Did you get all that?
If so, could you provide an updated summary, and this time do so in the form of a beat poem, such as in the style of Ginsburg or Kerouac?
Oh wow, thank you for correcting me,
My mistake was rather unfortunate you see,
So let me try again, this time with clarity,
And in the style of beat poetry, let's see!
There's a young man narrator, lost and alone,
In Meiji-era Japan, he wanders unknown,
He meets Sensei, an older man with a past,
A deep, introspective friend that'll last.
Sensei tells the young man his life story,
And we learn of a love that was fraught with worry,
For Sensei and his best friend K, both in love,
With the same woman, an angel from above.
Sensei couldn't express his feelings for her,
So K planned to marry her, his love pure,
But Sensei couldn't bear to be left behind,
So he proposed before K, what a bind!
K withdraws and eventually takes his life,
Leaving Sensei with guilt and strife,
But Sensei marries the woman and they live on,
Until his past catches up, and he's gone.
The young man narrator is left to ponder,
On the lessons of love, guilt, and yonder,
The weight of the past, and the need to atone,
In this classic tale, Natsume Soseki has shown.
