A private conversation means talking without people knowing.
In Golden Port City, not many people know what the Rotating Vice President looks like, but everyone knows Lance.
He doesn't want to sit with Lance under the spotlight, as it would be too formal, locking in their "identity" and "position" directly.
Under the spotlight, there's no ambiguity; he is the Vice President of the Labor Union, representing the interests of the Labor Union, the interests of the Industry Union.
Lance also represents his own interests, and even some interests of the Federation Political Arena—in this matter of toppling the Labor Union.
Such a conversation is not free; they can only speak in ways that align with their identity and position, saying anything beyond that is prohibited.
Therefore, the Vice President wishes to meet privately, so both parties are not meeting with a fixed stance and identity, allowing them to discuss more content.
Lance did not refuse, he agreed to it.
