Another thing I appreciate about Persona 4–Saki Konishi wasn’t “nice”.
It should be obvious why I’m airquoting that. Saki’s treatment of Yosuke doesn’t define her as a person, but the player is inevitably left with a rather negative impression at first. And that’s just it–the game doesn’t continue to reinforce her as either an evil bitch or a virginal angel. There’s Yosuke getting over his feelings for her and what he imagined her to be, but that’s very clearly Yosuke’s issue and not her responsibility (or rather, the responsibility of her story) to deal with.
You see the harsher side of Saki, but through her brother and through the glimpses of her life you get you also see a person who’s missed very dearly. Yosuke’s crush–and her true feelings about him–don’t solely define her character.
