So after 300ish chapters we finally know WHY A-tan was in the Garden Palace in the first place and WHY she turned into a child. Or did I just forget already and it was explained before? Either way it was bothering me for a while - the reason A-tan was trapped in the palace and what she was doing there - so I am happy to have it off my chest.
What is bothering me now is why Yozora knew all that?! :O
