You, the reader, are in junior high. You get your first girlfriend, and it happens to be the infamous Nana. As you get to know her more, you find out that she wasn't as bad as you thought she was. But when you start to think she's a yandere(though you don't really believe that happens in real life), will you see her the same way as you did to the girl you used to love?
P.S. I originally wrote this in my other account, but I couldn't update it because I couldn't verify my email. So if you came here because of that, you can skip to the chapter where you already are.
