Certainly this manga is superb, but the ending leaves too many questions:
>Will he continues to keep her in his house forever?
>Will she ever grow? What will happen if she grows up?
>What will happen if her existence was known?
>Why does she seems so attached to him? What about her parents? Do...
This is getting interesting, served as a good backbone for future chapters, if this manga actually got axed that'l be a wasted potential on such a good manga like this.
