One idea could be to get your grandpa a BTS t-shirt, hoodie or cap. Alternatively, you could look for BTS concert tickets or merchandise, as he may appreciate the opportunity to attend a BTS concert or own a piece of the band's merchandise. You could also look for a BTS book or documentary that he can read or watch to learn more about the band and their music. Lastly, a BTS-themed photo album or scrapbook could be a thoughtful way to help him keep and remember his BTS fandom experiences.
Or you can get him a star map with an important date you share.
