I am an awkward nerd and find online romance borderline creepy, so I rarely partake in them. But there is one single moment which made go 'oh gosh', which is that if you dismiss Fane in Act 2 and then recruit him again, he will say that he's read about this type of inconsistent behaviour and accuses you of flirting with him. Which I found cute, mostly because I have ever only experienced in my life that if I start flirting with someone they immediately play along. No one's ever called me out. How do you know if you're getting somewhere if they don't address your attempts?
So yeah, cute moment. I think my favourite romance moment was when the Red Prince in a savescum to see what would happen
upon demanding his babbi gurl's life he immediately without any hesitation turned on us even though he was close to boning the male lizard of the party. Now that's romance; defending unborn babies.
