For overseas ELF:Basically, the girl’s boyfriend doesn’t let her go for the SJ concert and she ends up breaking up with him. Her boyfriend says that SJ is just a bunch of guys who take off their clothes on stage, shaking their butts, seducing girls. So her friend said to not insult their idol, saying that SJ is professional, they dance and sing all at the same time. He then questions her boyfriend whether he can do that as well. And the girl also tells her boyfriend that SJ is her idol, none of his business.
