The only other Persona games I've played so far are P4G and P4AU. I'm not as invested in ships from those but I do greatly enjoy Adayu as ambiguous or one-sidedly romantic on Yu's side, find Yurise pretty cute (I prefer it as one-sided though), enjoy Yu x Ai as exes or one-sided and like Souyo as one-sided from either side (but I also like it a lot as purely platonic).
