Need help getting into k-pop to impress my gf

Hey Reddit! My girlfriend is super into K-pop—like, she knows everything about it. She can name every idol, group, and even remembers all the choreography. I don’t know much about K-pop, but I really want to get into it so I can connect with her more and surprise her. I want to genuinely enjoy this, not just pretend to like it. So, any advice from seasoned K-pop fans would be nice.
