As the 16th annual GF Bunko New Authors Contest approaches, Itsuki Ä s girlfriend Nayuta gently supports him while a major slump is preventing him from writing any novels. Toki and Miyako try to find a way to snap him out of it, but the results are anything but good. Meanwhile, Chihiro undergoes a huge change now that she is no longer hiding her gender...

After giving up on becoming a protagonist, Itsuki continues to listlessly churn out novels like a machine.

Though our main characters have stagnated, the world keeps turning and time marches relentlessly forward...and whether they're aware of it or not, big things are in store for Ashley, Nadeshiko, and the Hashima family.

Winter ends, spring arrives, and our protagonists take a new step forward. Haruto announces a new series. Miyako joins Branch Hill Publishing to finally become a professional editor. Chihiro becomes the life of her university's TRPG club. Finally, a 100,000-character love letter inspires Itsuki to pour more energy into his novel and become a genuine protagonist. A new everyday life dawns as the series enters the first half of its final chapter!

Even after making his break as an author, marrying the person he loves, and becoming a father, Itsuki Hashima has not changed and continues his regular routine of writing novels. But how about Chihiro, or Miyako, or Haruto and Nayuta and Ashley? Not to mention Kaizu, Kaiko, Setsuna, and Nadeshiko?! How much or how little have they changed? What kind of future awaits them?
