To be fair, that was an oversight from the Morenatsu Revisited days. The description will be changed upon the next build's release, which I am working on still. Unfortunately, I've had a bad run of luck with my health over the previous months, which has led me to need to resign from my job.
It should read "[...]before completing your senior year at high school."
Lesli-Chu!?, our main composer and assistant writer, has actually been helping me with some of the content while I've been unable to work on the project. He's been absolutely amazing, and I would like to assure that there is actually going to be quite a nice bit extra. With the extra free time, I'm hoping to be able to be more focused with Homecoming.
