This isn't exactly the best story. The synopsis gives you false hope that two siblings grow together to love each other and respect one another through some hentai-ish content that the sister is obsessed with. Yet you're sort of toyed with, when the author introduces this sort of strange sexual undertone between the siblings, that doesn't grow into anything, but is still present throughout the manga. There are parts that are downright kind of boring, and to be honest, I finished the manga cause I knew it was only 26 chapters and I can just power through it quickly when I was bored. The art isn'tgood, it's pretty sloppy actually. Some fuzziness on some scenes and strange faces were drawn for some characters.

Characters is what should be driving this story, and even though I put the characters as "decent", they weren't worth the read.

Overall, it's a poor manga. I'm not recommending it, especially with a lackluster ending.
