I will say that those storyboards seemed a tad excessive.
I think those are mostly figuring out what they need for various NPC... ekhm... configurations. Actual direction (shots etc.) will probably be more cinematic then just shot of them humping.
Still, I actually quite liked verbose romances in D:OS2. Especially spying on Red Prince was straight up hilarious. Whatever Larian does I hope they won’t loose creativity on the way.
