They became controversial last year because of their lawsuit against SM Entertainment. Micky Yoochun, Hero Jaejoong, and Xiah Junsu, specifically had some issues about their contract with SME. Theirs was dubbed as slave contracts. I can't really remember the details, I don't want to read more about too because I know I'll just be sad. I like them. DBSK, like Super Junior, are also brothers to each other, like family. But it's been a while since they performed as 5 in Korea, it's been awhile since they released and album in Korea or even attend a variety show. I just miss the dorky, cute, and funny DBSK and amidst all the controversies, I hope they will come back someday. I want to see them in variety shows, music shows, and concerts again.
Here's one of their oldest songs, Hug. I love this song. I miss DBSK. >_<
P.S. Did you know that DBSK has the largest fan base in the world? That's how lucky they are. So many Cassiopeias love them. :]
