Despite advancing to a new grade, I still ended up in the same class as my childhood friend, Shinon—a relationship that's more of a nuisance than anything. That day, sudden heavy rain left her completely soaked. Since her house was quite far and it felt cruel to send her off like that, I decided to let her into my place. Though she gives off a slightly gyaru vibe, deep down Shinon is actually incredibly cute. Even though she was wearing sheer lingerie like transparent bras and panties, I'd never seen her as a romantic interest before. But seeing her figure that day, I began to view her as a woman for the first time. Realizing I might never get another chance like this, I decided to cross the line.
