On December 8 episode of tvN's television show 'You Quiz on the Block', AKMU made a guest appearance.

She continued, "When we used to go to meetings, everyone used to look at Lee Chan-hyuk for his briefing. I had no idea that the eyes would come to me when he wasn't there."
She went on, "I felt really heavy on my shoulders at that time. I felt super pressured. I didn't know Lee Chan-hyuk had to go through all that before I experienced it myself."

Lee Su-hyun said, "I thanked him for everything, and said I was sorry for not knowing all the things that he had done for us."
She resumed, "At that time, I honestly felt like he was the only songwriter who knew what sort of songs that would go with me well. After that, I came to have great respect for him."

Lee Su-hyun said, "I believe I was completely immature then. I think I was being like a thoughtless little girl. I just kept questioning myself when Lee Chan-hyuk was away in the military. I was like, 'What is real me?', 'Were they anything I began doing simply because I like doing them?' and so on."

The duo joined YG Entertainment following their appearance, and made their official debut with an album 'PLAY' in April 2014.
