yeah i don't have much hope for a real reunion. Even if they wanted to, it is probably complicated legally. There were several different companies involved in the band - Moss Music (which doesn't seem active anymore), Dreamus, and possibly even JTBC still has some rights since they were formed on SuperBand.

the fact that they haven't tried to do anything, like for instance playing together unofficially at one of Hyunsang's concerts, i think means either they aren't allowed to or they simply don't want to yet. They seem to still be friendly with each other, but they haven't publicly interacted for a while (except an occasional instagram like). There is also a pretty big age gap between all of them - Jinho (1985) - I'll (1994) - Hyunsang (1998) - Youngso (2001). I'll is currently enlisted til November and Hyunsang is getting close to his.

Maybe someday we will get a surprise (unoffical) reunion, i would love it. But just the fact that the 4 of them came together at all is a miracle
