When I was in my second year of high school, I underwent a very unusual health examination. The teachers called it a "special health check" or a "development survey," and the content was something that shocked us. We were given a request form in advance, and told, "Please discuss it with your mother, and if it's okay, get her signature and bring it back." So I talked it over with my mom and got her signature. At the time, we thought lightly of it, saying things like, "Being selected for the prefectural examination is an honor." But in the end, the health check we went through was extremely special.
