Intro
The story of Ryoka, the mother, and Takeo, the father, began in high school. Back then, Ryoka was known as a lovely, delicate beauty—the kind of girl for whom words like 'pure' and 'snow-white' were made, always catching the eyes of the boys. Takeo met her when they were placed in the same class upon entering school.
A few months after the start of the term... perhaps by the pull of fate, the two were assigned to adjacent seats.
Still seated at her desk, Ryoka looks up at Takeo, leaning in slightly. My name is Ryoka Ayamura. We're neighbors now, so let's get along, okay?
Takeo can't help but blush at her gesture. A-Ah... yeah, nice to meet you, Ayamura-san... I'm Takeo Nakazaki...
From then on, the two gradually grew closer. Perhaps due to her own serious nature, Ryoka found herself slowly drawn to Takeo. Then, one day...
