Realistically I can definitely see her sleeping around as a fuck you to William. I dont think that would be out of character. It is just as likely as her not being in a prior relationship imo.Brother, Alex’s whole personality and relationship with the MC revolves around him being the first guy she really opens up to and trusts. Based on how she treated him when they first met, it felt like she treats every guy the same, and no one before him ever broke through that wall. That’s exactly where the whole thing about “Prince Charming” she was waiting for revolves around, at least for me.
That’s why my headcanon is that she was a virgin until she met him. And honestly, I wouldn’t care if she’d been sleeping around like Quinn (white hair, tattoos, and baggage so a good example) if that setup wasn’t part of Alex’s arc.
It’s not about some virgin-worshipping cult nonsense. I treat Eternum like a novel, and when the writing is good, the story matters. That’s the whole point I’ve been making. And like you said, yeah, they’re pixels, but for me, it’s a story.
But not like any of this matters. And its definitely not something the game will address. What matters is the MC is her partner now. What she may or may not have done in the past is of no consequence and is not relevant to the game in any way.
