Rose forced a kiss on Finn without his consent, and it was especially awkward as there was not even anything between them throughout the movie.
Calling it sexual assault is disingenuous af and people saying it are indeed trying to "out-woke" the movie as another poster perfectly put it.
And Rose absolutely has an interest in Finn from their first scene as she's enamored by his involvement in the Starkiller Base shit from TFA. She thinks he's a real ass hero like her sister but quickly realizes his self interest trumps everything else with him trying to abandon ship.
IMO, Finn's interest in Rose is their on paper but Johnson and Boyega do a poor job in those scenes in conveying that. The scene on Canto Bight where she's describing how she wishes she could "put [her] fist through this whole lousy beautiful town" (one of my favorite lines in any SW movie) has Finn looking at her in what I assume is meant to be the moment he begins to be inspired by her beliefs (and by extension, her) but Boyega's just got a blank stare on his face. There's also the scene with DJ on the ship where Rose gives him her necklace and Finn gets pissed and confronts him. There Boyega is fine but it comes off more like a older brother / protector thing rather than him getting worked up due to more personal feelings.
Then there's final scene with Finn looking over Rose as she's passed out from saving his life (mirroring the imagery of Finn being passed out and Rey watching over him at the end of TFA) that is clearly to leave a door open for those two characters' relationship to develop further in the sequel, but that's apparently completely killed in some filler book that the vast majority has no idea exists.
I can agree with saying it's shown to be one sided but to say there's absolutely nothing there prior to the kiss is wrong. And no, that doesn't make it sexual assault which again is a dumb and disingenuous reading of it meant to solely be inflammatory.
