Sensei mo Shousetsu wo Kakun desu yo ne?

Sano Masamichi, an unremarkable cram school teacher, decides to attend a signing event for his favorite novelist, Kotoba Mitsuru.

There, he unexpectedly encounters Mitsuharu Kotone, a student notorious for napping in his class. To his surprise, the genius bestselling author turns out to be none other than his own high school student! They had crossed paths once before, sharing dreams of becoming writers. However, Kotone, unable to accept that Masamichi has given up on his dream, takes an unexpected action:

“Write something for me. If you don’t want your life to end with just this photo…”

Using this leverage, Kotone draws Masamichi—who already has a girlfriend and a stable life—back into the world of writing.

“Return to your ordinary life, or become a novelist with me. What will it be?”

After struggling with his decision, Masamichi finally chooses to pursue his dream once more under Kotone’s guidance. Through this journey, he begins to realize that within his student’s eyes reflects an entirely different world...
