Ahh, you mean the Step-by-Step one haha forgot that one existed
Yeah, that document isn't a "Walkthrough" in the sense of things happening at those exact time frames but rather it happened to the guy making it on that day, think of it more like a log of his activities rather than a proper walkthrough/tutorial.
If you check the guide (link in the 1st post of the thread) and then click the "State Event" spoiler you'll see it says that both the MC and the girl in question NEED to have 70 points each and have all the previous scenes with her already done. No worries about it tho, I was just a little bewildered since it was the first time someone mentioned the "25th day" haha
