In a recent interview, rookie group JJCC opened up to several topics like being produced by Jackie Chan and the reason behind their selection of the track, "At First" as their debut song.
With the relation to Jackie Chan, SimBa stated, "He is like an older brother and father to us. There aren't that many opportunities for us to see him in person, but he gives us a lot of advice through videos. When he visited Korea recently, he took care of us, taking us everywhere along with him for his schedule except when he was sleeping."
E.co also opened up on how this link between the group and Jackie Chan made them feel. He stated, "It was very burdensome . . . We are also cautious about not doing something well even a little bit in case we cause a blow to Jackie Chan."
Also, it was expected that the boys would take the perform a fast-tempo song and energetic performance, however they released a mid-tempo song, "At First." With this,mSan-Cheong stated, "I think a lot of people were surprised at our performance. However, we thought it'd be too obvious, so we used our brains a bit. We are the idols raised by Jackie Chan, but we wanted to show right off the bat that we could do other things besides showy performances."
