You shouldn't be to amazed by the f

You shouldn't be to amazed by the fact of him not knowing. Just put it this way. Things clear out in Ayano's Theory of Happiness for why she would do that. And that it is being that song the last from the album. It's not so weird for people to not understand what's going on. I think we all have passed through these songs a lot of times before realizing what it really meant. Even though, you did a great thing in telling him where do all this come from, since he can look for it not. :)
