Intercultural Relationship with a Bihari Partner

I'm a 27-year-old South Indian woman, and I was recently asked out by a 25-year-old man from Bihar. He is nice, Smart and we vibe well together.Since I’m not familiar with Bihari culture and traditions, I’m wondering what it might be like to be in a relationship with someone from that background. I see relationships as long-term commitments, so I’m curious if anyone has experience being in a relationship with someone from Bihar. How did it work out, especially when it comes to cultural differences? Additionally, we belong to different castes—he’s from the Yadav community, and I’m from the Velama(forward)caste. How might this affect things in the long run, especially when it comes to marriage? Am I overthinking this? I’d love to hear your suggestions, insights, or personal experiences.
