I wanna cuddle on Pantalone’s lap in his office and then a Fatui Agent or other lackey walks in whilst I'm there, all while Pantalone is perfectly at ease conversing with said Fatuus who is trying to decide where to look and whether to acknowledge your presence...
On one hand, while it's certainly not an explicit scene, it's definitely a step or two up from linked arms and the occasional peck on the lips while you two are in public. That, and the way the Regrator reacts when someone's gaze lingers on his darling just a little too long-- some days he can't help but rub it in that you're unobtainable, some days he's proud to have such an attractive lover, and some days he really dislikes having people leering at you.
On the other hand... it'd be rude to not at least say hello, right?
The safest option would be an offer to come back later. It's not exactly a life or death scenario, it's just a field report. Hell, they can even just leave the report with Pantalone, say their piece, and leave. Wouldn't take more than five minutes tops.
Unfortunately, Pantalone is in a good mood (it's anyone's guess why that would be the case...) and when he is in a good mood, he likes to talk. He also talks when he's in a bad mood, or a neutral mood, or if he has the freedom to open his mouth. He wants clarifications, confirmations, and corroborations, all while you're still perched in his lap, an arm around the small of your back to hold you there. The poor agent settles on looking at the report itself, better to think they're just awkward rather than make the decision to acknowledge your presence and flip a coin on if the Regrator will be appreciative or not.
It's not until Pantalone dismisses the agent that they acknowledge you. They bow and thank the Regrator for his time, then they give you a smaller bow before promptly leaving the office. When the door shuts, Feofan can't help but laugh at how flustered that poor agent seemed. You roll your eyes, your face also warm with embarrassment. That warmth blooms into a heat when Feofan pulls you in closer and begins kissing and nuzzling into your neck. You just hope there's not another poor agent who needs to bring in a report, because you're going to be here just a little longer...
