I mean at a subconscious level, they have feelings for each other – a good chunk of the show is them dancing around that concept. That being said, all they both know is that it’s a marriage of convenience – neither knows the full identity of the other.
Yor constantly worries she won’t measure up to Loid’s needs, and that’s a risk to government scrutiny by the secret police. Loid worries his relationship with Yor doesn’t look airtight, and could compromise Operation Strix. Everything they do publicly to prove their relationship is legit is an act in which any enjoyment is a secondary benefit (like the scene above).
Definitely noticed that with Mastodon – there’s not a whole lot of folks talking/reacting with one another. I suspect it’s related to the user base (doesn’t have critical mass, demographics, or activity) or a discoverability issue. Bluesky, on the other hand, has a whole lot more engagement on a host of topics.
