Well, we know that there's going to be 2 throuples. Ines+Vi wouldn't surprise me, but 3 other plausible ones come to mind (Amrit+Ines, Amrit+Kana, and Vi+Elspeth).
Amrit and Ines have been spending a lot of time together and growing closer. Oh yeah, and if in Mallorca during the pool scene you didn't look at Amrit or Ines, go back and do that. Can't take a screenshot now, but
pretty much Amrit and Ines lean on MC, hold hands while groping MC, and gaze into each other's hooded eyes across his chest. If it hadn't been so early in the story and Vi hadn't been there, I would have expected a threesome to break out at any moment.
