At first I thought it was a passport bro on vacation, but it turns out it was a love affair (cheating).
Everything about this is disgusting and whoever pushes this shit as some kind of romance needs a kick in the butt.
The word "affair" does not appear in the transcript of the episode; my only guess is that the commenter googled the name of the story looking for a summary and saw "love affair" in some of the results.
