Tried to watch the episode, but they talked too much
Yunoha speaking as a boy was cute anyways ahaha.
But speaking of the episode I don't like when the writers decide to dedicate an episode to explanations alone. Like in Guilty Crown. I prefer having it little by little.
Anyways, I agree that writers have failed a bit on the romance side. The only explanation I could find is that they decided to handle the romance with an episodic format. So, if you are going to re-watch only Jin and Yunoha: select ep. 12/13, Mix, MIX-Y and Andy: select #bla #bla #bla. Amata and Mikono, 1,2 etc etc. Similar to omnibus format, but with different couples.
Anyway, even if I don't like this kind of formats, I still have faith that they will handle in some ways the last episodes. But I don't care of reincarnations.
