In The Rules of Acquisition, the female Pel breaks the rules of Ferengi society by putting on clothes, and demonstrating that women are equally good at making profit.
She falls in love with Quark, and it's clear that he has feelings for her, too, but she boards a transport at the end of the episode.
Why couldn't she just stay on the station?
In universe, I mean. I reckon the showrunners didn't intend to add another cast member (and fourth Ferengi), and Quark couldn't behave in the usual horny fashion if he were attached, which would dampen the character in the narrative sense.
The real life reasons for Pel having to leave make sense, but in universe, Pel and Quark were a good team.
