Yori's attitude has changed. He and his twin sister, Iku, used to be inseparable as children, but lately Yori's been different—eager to be apart from Iku. Iku worries that he hates her, but the truth is far more scandalous. Now, Yori would risk losing everything to have his little sister. Iku loves her big brother enough that she would never risk losing him, and so she'll do what it takes to keep them together... but Yori doesn't want to have her that way—as a sister dedicated to her twin. Can Iku ever love Yori not as a brother but as a man?

When it comes to romance stories, I've always enjoyed "forbidden love". Be it between the same sex, step-siblings, student & teacher or cousins; I tend to enjoy these flavours over the vanilla stuff. So here I have Boku wa Imouto ni Koi wo suru. A Shoujo, Romance, Drama themed around the forbidden love between siblings and yet I did not enjoy this as much as I hoped.

Although Boku wa Imouto is a shoujo manga, it mostly follows the point of view of our male protagonist Yori Yuuki, where it is immediately apparent that he feels strongly for his twin sister Iku. So strongly in fact read more

My inital review of this manga was rather poor, but now I'm glad that I've finally finished the whole series. I have to say that the later chapters have the "roller-coaster" plot that kept me going.

Yori's love for Iku was that of sacrifice, for a better future for her; while Iku had to find her own strength and determination to prove her love for Yori. Their deep love came with a hefy price tag; alongwith challenges which will test if their love was true.

The author left the ending to reader's imagination; thou not the perfect ending but I think it is good enough.

SO, GO READ read more

Never done a review before, and normally I would format it a bit better but I can't be bothered since it wasn't really worth my time reading 49/58 chapters thus so far. The only reason I read it was because I thought it was this manga I read a long time ago, but it didn't turn out to be and I thought I'd at least finish it. I thought I'd at least write a review to get a different opinion out there. Albiet, this is a work of fiction, it's still incest and I believe it should be taken seriously, so here is read more

Ending is bad and author should feel bad.

lulz are nice, but plot - average (just a bit smarter, than that of a mere manga)

Multiple fertilization, wtf
