On the July 30 broadcast of SBS funE’s “School Attack 2018,” NU’EST W infiltrated a school to treat the students to a surprise performance.

Before the big reveal, the members were each tasked with missions to complete inside the school, during which they had to remain undetected.

JR and Ren entered the school first, their mission being to find the signs on the stairs with NU’EST W’s lyrics and take a selfie, and also to place their own sign with handwritten lyrics on a blank step. Though JR passed by a faculty member and Ren had a near run-in with a student, both successfully carried out their missions.
