>>30384886Shu would be the author avatar character, Elira is drawn to be based on the mangaka's gf or his ideal waifu(as explained in one of the Author's Note pages). Even though they don't interact much and are barely present in the story at all, a certain subset of fans insist they get together and seethe when they don't even show up in the epilogue.
Vox, Reimu and Ike are involved in a b-plot. Reimu has a crush on the popular guy Vox and spills her spaghetti whenever she talks to him, she goes to his friend Ike for help but overtime Ike and Reimu start falling in love instead. At some point this whole subplot gets dropped and never concludes because it turns out the mangaka doesn't like Reimu that much and didn't know what to do with her. A different mangaka is contracted to write a spin-off about them.
