Kimi to Kore kara

Kimi to Kore kara summary:

From September Scans; Here starts the Konya spinoff series, focusing more on Gorou and Verde! There’s plenty of Endou and Rikiya as well, but this story will spend more time telling the story of these heretofore side characters. The story takes place immediately after the last Konya chapter, so you can think of this as Chapter 20, just less focus on Endo/Rikiya and more on Gorou/Verde.
