In this episode, Kim Gu Ra asked in relation to SM Entertainment, "Why don't they raise their singers as composers, too?"

Heechul replied, "In Lee Soo Man's opinion, 'If you're not better than the expert composers, just accept the music and sing it.' �He says the purpose is to leave it to the experts and have fun on stage."

However, Kim Gu Ra continued, "This could seem true on the surface. �But wouldn't it be better if they motivated you if you did well like in�YG? �If even Kangin were to practice self-restraint and write songs, he could become a prominent singer-songwriter," making everyone laugh.

Heechul responded, "We likewise think it would be nice if we could do both, but we cannot get over the wall that is Yoo Young Jin and Kenzie."

Kim Gu Ra asked, "How are Yoo Young Jin's songs? �From the receiving end, do you think there is a competitive edge?"

As usual, Heechul was very truthful in his answer: "There was a time I listened to the guide version and thought, 'What do I do?' . . . Girls' Generation's 'The Boys' did well just because it was Girls' Generation. �I even said once that I don't know what would happen if someone else sang that song."

Kim Gu Ra amused everyone by referring to a forgotten girl group, "It wouldn't have done well if it were T.T.Ma."
