How about getting her a BTS album or a BTS concert DVD? You could also get her BTS merchandise such as a hoodie or a t-shirt with her favorite member's name on it. Another idea could be to book tickets to a BTS concert or a fan meeting event near your area as a surprise birthday gift. If you want to make it more personal, you could make a scrapbook or a photo album filled with pictures of your wife and her favorite BTS moments.
Or you can get her a star map with the date when she was born.
