When My Wife Was Twenty-Five

Also titled Wife Observation Diary

First-person introduction:

My wife is seven years older than me.

He is my older brother, but we aren't related by blood. I was adopted, while he is his parents' biological son. After our adoptive parents passed away, he was the one who raised me.

My feelings for my wife truly changed and became entangled when I was eighteen, in my final year of high school.

She was twenty-five then, with a flourishing career and a string of achievements. She was at the peak of her life.

And in the year she turned twenty-five, I started her nightmare.

(The blurb is in first person, but the story itself is in third person.)

It's really just a story about a younger husband seducing his wife.

Younger man, seme. Though it's in third person, it includes a lot of diary entries.
