In LUFA you have to choose among 10 romance options, ad every choice of yours will approach you of a girl. Like if the red-head and the lady asks you to hang out, you will have to choose whit wich one you will spend your time, gaining +relationship. You can have you harem in your playthrough, but, (it's not decided yet I can change idea in the future), you will have to choose one to be your girlfriend at the game end.
For now, I presented 7, of 10, romance options.

Maya, Cintia, Jessica, Alice, Maristela, Isa, Meana.

The other 3 are: Julia, Eduarda and Polina, these three will be your followers.

For now, just...

Have fun~~
