What is the author's style in Confessions of a Mask by Yukio Mishima?

The story is told from a first person perspective. The narrator is an older, wiser version of the protagonist himself, ostensibly relating past events from his own life. Most of the narrative is rooted in the "now" of the protagonist, focusing on the story as if it were unfolding in the present. The reader does, however, get the occasional glimpse of the future when the narrator interjects to provide commentary or explanation.
