Not long ago Ocean said that he no longer discloses information about new LIs and the current LI changes. He also said that, most likely, those LIs that were originally planned will remain in this status.
If I remember correctly, the recent LI list looked like this:
Bella, Nami, Vic, Mila, Sasha, Sonya, Zara, Vanessa, Nia, Nadia, Amber, Marla and suddenly Elsa.
And don't ask me why Maja or Ayua isn't there, I don't understand this either
Ocean wrote several times, that the game isn't a dating sim, so the stories of certain main girls will develop at different times, in accordance with the plot. So yeah, the first season is mostly Bella-centric, but other girls will get their fair share of the screen time in the following seasons as the story progresses.
