According to a report from Naver, Member "N", a drummer of a famous band, reportedly forced a traditional musician to take off her clothes multiple times in places like the practice room. She states in her most recent occurrence that "N" asked her to take off her clothes. He was also holding a cell phone. She said she didn't like what's going on but he said things like: "Just for 5 seconds... or 3 seconds... you dont want to?".
"N" is unreachable right now because his phone is off.
Comments in the articles are stating "N" is likely from an older band and/or middle-aged. "N" wears glasses and is bald so highly likely that "N" is not an idol.
