How about getting your husband a K-pop concert ticket or some limited edition merchandise from his favorite K-pop group? You could also surprise him by creating a playlist of his favorite K-Pop songs and adding some personalized messages in between. Another idea could be to gift him a virtual meet and greet session with his favorite K-pop artist. If he enjoys Korean culture as a whole, you could consider taking him out for a Korean dinner or even plan a trip to South Korea.
Or you can get him a star map with the date of your anniversary.
