P3 - Mitsuru or Maya. I just really like the both of them.
P4 - Ai. I know a lot of people don't like her, but I find her kinda relatable.
P5 - Haru. Every choice in P5 is fanominal. Exept Futaba she is too much like sister to Joker for me to even consider. But Haru was the only one that ripped my heart out when I didn't go for the romance rout.
