They are like an immersive experience on their own
BTS: https://ibighit.com/bts/eng/
Enhypen: https://beliftlab.com/artist/profile/ENHYPEN
Le Sserafim: https://www.sourcemusic.com/artist/profile/LE%20SSERAFIM
They put all the information about each release in one place (album description, all concepts teasers, tracklist)
And it's so easy to look through everything, because all the photos and videos are embedded into the page and clicking lets you zoom in (to a slideshow)
And there's full translation in English, Korean, Chinese, and Japanese
They went above and beyond a regular professional website

It's so gorgeous
If you go on Enhypen's discography pages there are even animations on the text
And by the way, Pledis groups websites (Seventeen, fromis_9) look a lot more typical
I know about NewJeans.kr too but I didn't include it since it's a different type of design
