BTS members RM and Suga appeared on the YouTube channel 'Epik High' in the content 'Epikase' and revealed their pre-debut stage names and stories within the group.

In the broadcast, RM disclosed that his pre-debut stage name was 'Runch Randa.' He explained that the name was taken from a character he created with a friend. In response, Mithra Jin reacted with laughter, saying, "What? Are you having lunch?" Suga shared that he used the name 'Gloss,' inspired by his real name Yoongi. Tablo commented, "Suga is much better than Gloss. If you were Gloss, you would have been in big trouble by now."

RM also mentioned that he recently obtained his driver's license and shared an anecdote with Tablo. After drinking wine with Tablo, when RM asked how he would get home, he found out that the person saved as 'Driver Kang' in Tablo's phone was actually Tablo's wife. Two Cut jokingly said, "Assassination attempt," and Tablo laughed, saying, "Are you trying to wear me down like this? That's too much."

Conflicts among BTS members during the LA song camp were also revealed. RM said that he suggested wrapping up the night after drinking to prepare for work the next day, which upset Jimin and Taehyung. Suga explained that all the members were drunk at the time, so although they didn't know the exact reason, emotions ran high. RM said, "I became the villain of the world just for suggesting to end the night," and mentioned that the two members expressed their feelings of hurt for three hours. Suga added, "I kept asking 'Why?' while watching. It didn't seem like the time to fight, and J-Hope just went to bed early."

The broadcast also included playful questions and interactions among the members. RM said he thought he would lose in a hypothetical battle against Jungkook and said the outcome of a battle with Jimin was unpredictable.

At the end of the broadcast, BTS members shared various episodes with the cast, continuing the stories about their pre-debut stage names and group anecdotes.
