Onto the reason why he cried on stage, Jun commented, "I cried because the hyungs who got eliminated came to see the performance. The stage light was directed at me and I saw them sitting in the front row. They cheered for me by holding up my name tag. I think it hit me then. I still feel like crying just by thinking about it."
