On this morning, all artists scheduled to appear on the upcoming episode of 'Music Bank' showed up for the traditional rehearsal route, during which fans can greet their artists good morning, while reporters also take snapshots of the artists in their casual or stage wear. However, once Wanna One's van door opened up and the members attempted to get out, reporters on site stated that fans climbed over the safety fences set up in Wanna One's path. They stormed the van's door and crowded around it, using their cameras to snap photos of Wanna One.
Due to safety hazards, the onsite security ultimately decided to make Wanna One re-board the van and shut the door, after which the van had to drive out from the KBS entrance. One representative of YMC told news outlets, "It was impossible to carry out the morning photo line event due to a portion of the fans and their unwarned actions. Due to this, Wanna One boarded their van again, and had to enter for rehearsals through another entrance."
Wanna One fans have been demonstrating rowdy, unsafe behavior where ever the members showed up, from 'Happy Together 3', 'Weekly Idol', 'Give Me a Meal', and more.
