I also like the NicoNozo pairing but this doujin was awkward to me - specifically Nozomi going after Nico right after she broke up with Maki. Normally you’d wait a while before doing that, since this way it feels like Nozomi is taking advantage of Nico’s state of mind. At least Nozomi does admit that “It’s a horrible thing to say”.
Also Nozomi’s love epiphany could’ve been written better. Usually the angle is “I just realized I like you, but you’ve already started to date someone else”, but Nozomi realizing she liked Nico after they broke up seemed a bit odd to me.
Still, all of that being said I didn’t hate this doujin, and it definitely had its cute points.
