The Block B member and IU are collaborating for his upcoming track "Soulmate", and the 'Knowing Brothers' asked how he was able to get IU to feature in his song. Zico expressed, "It's coming out on the 30th. It's titled 'Soulmate'. We talked a lot. Before my debut, I featured in her song 'Marshmallow' as a rapper before, so we've been close since then."
Kang Ho Dong then asked, "Does IU have any interest in 'Knowing Brothers'? I met IU at the airport once, and she told me she was having fun watching 'Knowing Brothers'."
