Kuroki Tomoko thought she would instantly become popular once she entered high school... but the reality is that, two months after starting school, she still hasn't spoken with any of her classmates. As other kids in her class laugh over photos from their recent karaoke outing, Tomoko sits alone reading a book while she eats her lunch. That's when she decides it's time to take action so she can learn to converse with others - especially boys.

The culture festival is over, and it's back to life as usual. As fall sets in, Tomoko asks herself what exactly she's been doing all this time, and begins to feel like her life is flashing before her eyes... Making the decision to focus on the future instead of regretting the past, Tomoko finds a future plans questionnaire in her school bag. She decides to call Yuu-chan to see what she thinks, but is reminded of a past she'd have just as soon forgotten...
