If you liked the Da Capo anime, the Anime-Planet community thinks you'd like:
It’s a new year, and a new group of students is moving on to high school. Takaki Kono is a shy young man who has a variety of friends including the perverted Yuuji and overly-emotional childhood friend Konomi. Along with the usual responsibilities of attending classes and studying hard, Takaki finds himself involved in the lives of many young ladies as well. Whether it’s with class representative Komaki, wealthy and combative Yuma, Yuuji’s confident older sister Tamaki or yet another girl, Takaki finds himself always caught up with a new girl and a new challenging or playful experience!
One guy. Two childhood females (infatuated with guy) who are referred to him as his sisters - these are the main heroines. Other females also like guy, but are much less important to the story compared to the first two heroines. Will his childhood friends confess their feelings or keep them hidden? That’s the dramatic part they share so keenly in common, taken directly from the routes in the visual novels. Female androids; those are present too, as characters.
