At Zico's concert at Seoul's Olympic Hall on August 11, IU appeared to sing their chart-topping collaboration track "SoulMate". He expressed, "I received a lot of help from her recently, and I'm thankful she even showed up to my concert. I also was a guest performer at IU's concerts twice before, and it was an experience that left an impression on me. I hope IU makes a lot of memories here as well."

IU also said, "I came a bit early and watched the concert. It was really good. It's really impressive that he was able to do so well for his first solo concert. I've really felt how impressive Zico's music is while collaborating for 'SoulMate'. I think he'll remain as a musician who really inspired me."
