If anything it’s the reverse I’d think. Just look at books without a Happily Ever After and how that’s looked down on, and why its a requirement for Romance publishers.
Romance isn’t exactly a respected genre. Misogyny has a lot to do with that but the genre’s tendency towards formulaic tropes doesn’t help.
And before you get to the Happily Ever After? It has to be a rocky road, with a break-up. It’s almost like the HEA has to be earned through pain.
