The two previously collaborated for IU's track "Can't Love You Anymore" from her recent album 'Palette', which earned a perfect all-kill on music charts. On the May 20th broadcast of SBS Power FM's 'Cultwo Show', Oh Hyuk said of their collaboration, "We spoke about collaborating for a long time, but our schedules didn't line up so we pushed it back. For her recent album, she asked me to help her out."
He continued, "We met on 'Infinity Challenge' and continued to be friends," adding, "She's really smart, but I haven't thought about what kind of musician she is."
