This is actually really sweet. I have a very soft spot for this pairing and this doujin in particular hints to a few problems for the ship, to be honest. The whole pairing off with their 'true ships', for one. Nico will always go to Maki and Nozomi will always go to Eli. Thankfully they broke that stereotype by the end. In the anime, Nozomi mentioned that she couldn't help Nico (with that flashback of her and Eli looking at a busy Nico handing out flyers in the rain), but thankfully this doujin rectified that.
On another note, I find the HonoRin pair to be so cute and loveable. If only, ay?
