That's actually a tough one to answer simply.
Yeah, there's gonna be sex in the game — no surprise there. But how it happens depends.
With some characters, you just build up enough trust (relationship level over 9), and something might happen — if the timing feels right.
With others, it'll be tied to quests. Maybe you help them, maybe they help you, maybe it's just a weird night. I don't always know why it works — sometimes it just feels right in the story.
It's not some checklist or repeatable system. I'm going for something more flexible, more alive — where scenes feel earned, not farmed.
So yeah… expect sex. But also expect it to mean something. Or not. Depends on who you're with.
