I've read the story's review and It really a good one,
I must say the review are accurately done.
Another good story is made thank you for this,
the story development is good though it still lacks from background of the both world.
Though it only been a 21 chapters I think I can tell this flow of story is really progressing, but reading the comment sections I figure out the update quality is not stable.
I really taken interest in the characters since they are mysterious yet very open, but after reading all the 21chapter I've noticed some wrong spelling, and find updated chapters to be short But other than that it is really good one.
