Yes! He was TVXQ's face _(FOTG)_ and main visual. Him and two other members _(Junsu and Yoochun)_ sued SM Ent. way back in 2009 and got blacklisted from appearing in any major broadcasting stations for about 13 years; there was a "JYJ Law" that was passed because of this. JYJ promoted both as a group and as soloists but weren't able to promote much in SK _(so they mainly focused on their Japanese market)._ We're slowly seeing that blacklist fading so hopefully JJ gets more variety gigs and get more fans through JaeFriends!!
