It's a decent manga that has an interesting concept but is too short to be anything great. The story is unique but due to how short it is, it doesn't give us a true ending. Twin sisters fall in love with the same man who happens to be an erotic mangaka. The sisters agree to model for him and the harem lifestyle begins quite fast. I like the younger sister the best, but I can see the appeal of both sisters. This manga does take a serious turn later down the road but it's remedied by its humor and final scenes. The best element ofthis manga is the artwork which looked like Tonari no Kawshiwagi-san. There's a prefect blend of cute and erotic elements woven in between comedic scenes. It's not surprising that the artist behind this manga is a woman.
