I am holding on to the fact that Renjun did say he was starting to feel better. Plus that fact that on his few appearances or sightings he's actually been see with different hair colors... it makes me think he's still had a couple of "non-public" schedules with dream at least while he's been away. I really hope he's been seeing all of the posters during the dream concerts saying how much we miss him and will wait for him and love him.
