Remind! I have been preparing to write this article for a long time (probably several years). The perspective is probably based on my observation of my classmates' sexual feelings. Most of the characters have prototypes. I have been planning to create a story since junior high school, and I only had time to write it after I finished the college entrance examination. Most of them are my classmates in junior high and high school. I have watched gay sex many times in the past few years.
