Both Kanghyun and Yonghoon are enlisted but they prerecorded a bunch of stuff. They were even on a mnet show that aired after they were already gone but were in the eps. I'm not too sure what the rules are over in Korea for mandatory military enlistment. Weves do see this song as them singing from the perspective of the fans. We are hoping for some 3we stuff but with rbw we don't know. Kanghun and Yonghoon filmed some content together, there's two parts each close to around 30mins on the Onewe channel, if that's something you'd want to react to.
