The 100% boys are already known for their precise, knife-like choreography, but this time, they've upgraded to an even sharper choreo, calling it the "poison choreography". They shared, "We named it the 'poison choreography' because it's very tough. When you watch it, you'll feel the poison spreading. There are several points where we have to sweep the floor with our knees, so we got pretty bruised up. At first, it hurt a lot, but now it doesn't. It must be because we've hardened for it." 

They also talked about changing their introduction, saying, "We used to say, 'Charge complete, 100%', but it was too long, plus a little embarrassing, so we wanted to do something new. We changed [the introduction] to 'We Back', since it means that we've made a comeback, and it works as a sort of alarm announcing that we've come to perform."
