K.will said he thought about who he wanted to work with and he felt Mamamoo is a group that’s good at singing and that Hwasa could handle pop-like vibes well. He said he’s really grateful that she helped even with such a busy schedule.
She came and recorded her part right after returning from an overseas schedule. He said he’s thankful for the support and the song came out fun/well.
