What I can say is, this discontinued manga is "MC love his hot and intelligent sister". I am not sure either there is a light novel or not, but I couldnt find any but anyway, I love how the storyline and plot in this manga. The author really masterpiece his storyline and plots. Too bad it is discontinued or cancelled so the plots is kinda cliffhanging and the storyline also halted. The arts and designs also awesome, that is including the manga framing. The characters are detailed especially the female characters, you can see the cuteness in the drawings. This manga is not hentai. It is basically anecchi but incest? It is not there.

I wish the author or publisher still continue this manga. I couldnt rate full because of the unfinished storyline and plots, but it deserve 5 to 8 rates atleast.
