We knew that with Hatsukoi Limited J.C.Staff basically produced a better Kimikiss (which itself received all sorts of accolades back in the day), but there's more:

[J.C.Staff] have modified an otherwise normal manga into a highly coherent piece, mixing up multiple storylines to make it less confusing, and even changing some events slightly. I feel rather bad about the original manga actually, because with that complex relationship chart, the series is clearly gunning for a long serialization. But the series was unfortunately cut short due to some reason, and so the ending feels kinda rushed. The anime ended more or less the same way, but the modifications made it completely tolerable. In fact, they made it superior to the original source itself [emphasis mine — Author]. It's rare that an anime can go beyond its source material, but somehow with Kimikiss (with its typical bishoujo game roots) and now Hatsukoi Limited, they pulled it off. J.C. Staff is having hit after hit in this genre for quite a while, I should enjoy more of their works.

Maybe when they're done with the lesbian stuff.
