Using one song I think was a strength in this, keeping it focused while getting beyond the surface level of the music and lyrics.
The voice acting I think gave a lot to the implications of things said - Raven's VA was delightfully smarmy and Cardinal's VA really felt like he was recently taken under someone's wing. Something I think more IF needs to do.
I did struggle with 2 thoughts. The first was that the dialogue felt very Stjepan Šejić in the sense of "let's explain the basics of SSC for the normies" which might have been a missed opportunity to explore deeper ideas around the dynamic. The second is that Raven seemed too toxic to give the standard line on safewords - maybe that's just my preference for toxicity in my romance fiction. (maybe this was due to the choices I picked?)
I'd love to see more stories with these characters - sort of a "spies, but they're dating" from the other side.
