"Antagonist" Diana?

Thoughts on antagonist Diana? She obviously won't be a nagito or kokichi type antagonist, but moreso on the fact that she has different views than Damon. She's more of an optimist, while Damon is more of a pessimist, although I'd say he's also realistic. He voices my exact thoughts while i was going through each of the official dr games in the past lol. Anyway, because of them having different beliefs and ideals towards their situation, i can see them clashing more often in the future, especially during class trials.

I can see it going like this: in Diana's perspective, Damon is the antagonist, but in Damon's perspective, Diana is the antagonist. And since we're playing as Damon, obviously, Diana will be the antagonist in this case.
