▍Creator's Comment

It's been a really long time...!
After my last work, the next project was scrapped about three times. I also recently started a part-time job, so it's become very delayed.
This simulation is a SFW story about ordinary high school students. There isn't a particularly special story, but I would appreciate it if you could play it once or twice if you're interested.
Have a great summer!
