How about buying him exclusive BTS merch or concert tickets? You can also gift him their latest album or their previous albums if he doesn't have them already. Another idea could be a personalized BTS-themed gift such as a mug, t-shirt, or keychain with his favorite BTS member's photo or lyrics from his favorite song. You can also plan a BTS-themed date night, where you both can binge-watch their videos, listen to their music, and eat his favorite Korean food. How does that sound?
Or you can get him a star map with the date of your anniversary.
