Momoland thinks the choreography for "I'm So Hot" is the toughest one yet. 

On March 28, Momoland and 10cm guested on SBS Power FM's 'Cultwo Show.' While introducing their new songs, JooE shared, "The key point of our choreography is the gun dance. You turn your fingers into a gun and shoot."

After performing the song live, Jane said, "The choreography is the toughest one yet." The DJs asked, "It seems pretty easy but why is it so tough?" The members explained, "It's because you have to throw out your entire body for the gun dance. It's very difficult than you think because it uses many hand muscles."
