futakoi alternative!

as the title say..
is this different from the anime "futakoi"?
anyone watched it? :?

well, it has the Futakoi female characters with a totally different main character, storyline and world

and the blonde twins (forget their name) are the main heroines this time

it's a lot funnier and crazier than the original

ah so it is different...
which one should I watch first you think?
