Spin-off of SaeKano light novel series focusing on the unlikely relationship between famed author Kasumigaoka Utaha and average otaku Aki Tomoya. Down in a rut and out of lacking creativity, infatuation develops after a fan-signing for 'Love Metronome' and Aki becomes the estranged "assistant" of one of his school's top idols. *Includes 12 side/extra stories and an epilogue.*

A slightly adjusted retelling of Saenai Kanojo no Sodatekata but with a heavier focus on Eriri Spencer Sawamura as the main heroine.

The up until now untold story of how Sawamura Spencer Eriri and Kasumigaoka Utaha met, as told from their perspective and how they personally viewed the events of the main story.

I've known Ta-kun ever since we were 10 years old. Even though we are now in high school, we still spend our days in his room, talking about nothing in particular. We are close, but our relationship is not quite as sweet as lovers… Why won't you notice me? I'm trying so hard to get closer to you! I am Hikari Shirasaka, 16 years old… It might be a little late for me to tell you this, but I think I've fallen in love with you, my childhood friend.
