@LysetteMartinez@CreeTheOtaku After one of the Live On Earth concerts in 2013, Yongguk was having troubles breathing and was given the oxygen mask. He wasn't hospitalized so I don't think it was too severe.
@CreeTheOtaku Yes they did. After their release of Unplugged in 2014, they filed a lawsuit against TS. But, it seems everything has now been taken care of.
