Well... i dont know why other people rate this manga so bad... but i think this like case of the "Domestic na kanojo" manga that people rate it bad because the story not like what they want.

So remember... manga is not a things that based on your opinion or something like that. Because manga is something that created by the mangaka based their emotion, feels and the story that they want to be created.

Ok first thing first.
This manga have a good Plot, and some plot twist on the lastest chapter that i read (20), in early chapter i think most people will think that boring BUT in this case, i think the bad of this manga is they make "introduction" with "plain" story, so people will think that plot will be same to next chapter.

In fact in lastest chapter, the story more enjoyable and i think this manga is quite good for some reason, because it added "INCEST", "Corription" (of course in this case if you know what i mean), and also this manga added some "lewd" scene not only for fanservice but for the story.

i think that's my opinion about this great manga.
i dont know why people rate this as bad... BUT i think, some people from the west dont know how to read manga. they only read what they want. and if the story goes to other way that they want... they simply rate that manga bad score... Same case like Domestic na kanojo...

i think that's all.. thanks :)
