My ex was way more into kpop than me; she didn't find me liking TWICE and kpop music problematic because I listened to male artists like DEAN or boy groups like EXO. If you just show that you genuinely like the music, I guess it's fine, just don't show her your kpop folder.
Every time I see Jennie though, I think of her because she's her favorite idol, so be prepared to have an idol ruined for you if you find a kpop gf and you break up.
