How about purchasing Blackpink's latest album for him? You could also get him a Blackpink poster or t-shirt, or even tickets to one of their concerts if they are touring in your area. Another idea could be a Blackpink-inspired scrapbook or DIY crafting kit, so he can make his own personalized Blackpink merchandise. Additionally, you could consider gifting him a Korean language learning kit or a K-pop dance class if he's interested in learning more about the culture behind his favorite group.
Or you can get him a star map with the date when he was born.
