Poor Nao right now Fujimura is seeing her chance with Nao but he's gonna be hurt and feel betrayed, I don't like where this is going

In life, as in this manga, people can't find happiness all in the same moment, and in situations like that one or two "have" to suffer in the present time. Anyway, as you can see from this chap or the first one, Nao has a suspect about the two, and Izumi either suspected his friend had feelings for her or she had feelings for him (because of how she's behaving in this chap too). I think in life when you try not to see or run away, things are gonna cone back. So, I'm not saying it's Nao fault, but ... You know...
