To be honest, the only way the writers could ever frame HW and Finn’s relationship in a weird pedo way is if she groomed him at a young age but that’s impossible considering how they met. Like HW saw Finn naked in a river, didn’t give a shit and just walked up to him to ask him about the flute playing. She also threatened to shove an arrow up his nose too. The writers framed it as them just slowly liking each other over time and then made it clear that while she liked him, she believed they shouldn’t fall in love. She obviously changes her mind later on but it’s established that she’s kept her distance from Finn for a while and likely didn’t start their “on and off” relationship until he was older.
It’s mostly irrelevant now since Finn is an adult like you said and most of the focus now is their relationship when he’s older.
