SONE-730 One day, I was suddenly confessed to by a modest junior who was one year below me… and over the next three years, I turned her into an excellent partner. Nagisa Airi

This is the 1,000-day story of how I finished training an innocent younger high school girl into my personal companion.

She may have thought of it as pure, youthful devotion, telling herself things like, I did everything for my beloved senior, or This is such a precious memory of my youth. But in reality, she was just keeping up with my endless appetite. The most innocent ones are the easiest to handle.

By the time she graduated, she had grown more polished, taken off her school uniform, and was acting completely different. To her parents: thank you very much for raising your daughter so properly and so well. I truly appreciate the three years of the high school girl image.
