Ar Tonelico 3/Quoga Love Interest Questions *SPOILERS*

I had wanted to get this game, but then I came across something...peculiar.

SPOILERS BELOW

Instead of having a cast of girls to choose your lady love from, (yes that's the part I'm more concerned with. What's a game like this without a true romance amidst the hilarious perversion?) you get two. Or three? Either way, those 2 girls each have "personas" that take the form of the rest of the female cast (Filament, lovely Yurishica, the geisha, the...knight...girl? I tried to remain spoiler free until now).

Those who know this already are those I'd like answering my following question:

Am I stuck choosing between Saki and Finnel in the end? Or can I have Yurishica as my chosen ultimate romance? Or even Saraptra? Not to knock Saki and Finnel. They're both cute as buttons. But I prefer matured women (unless it's P4, in which case I prefer Naoto).
Are my choices ultimately limited to Finnel and Saki (and maybe another?), or can Aoto and Saraptra watch the sunset together? (mainly just Yurishica and Saraptra)

No. Yurishica etc are part of their main personas, so you gotta end up with the original one.

Well, except if you choose this one girl you'll end up with the not-so-original one.
