On a recent episode of NCT 127's YouTube content 'Johnny's Communication Center', the members decided to enjoy sledding in Chicago during their U.S. tour.

While most fans were delighted to see the NCT 127 members having fun on their off day, some fans were shocked to see a sasaeng fan caught on camera, un-blurred. 

For some, this foreign sasaeng fan is already well-known for incessantly stalking NCT 127, severely invading the group's privacy. But for other K-netizens, the appearance of a sasaeng fan on the camera, and un-blurred at the unlike all other civilians and staff, came across as a great shock. 

K-netizens responded with comments like,

"I thought she was a staff member at first... I'm so disturbed right now."

"If someone followed me around like that, I would be so scared to go outside."

"How are the members mentally okay acting like nothing's wrong when someone is literally stalking them that close..."

"Sasaengs all have serious mental issues."

"I'm getting goosebumps."

"Did they purposely not blur her face??"

"I'm scared that she might actually enjoy being on camera like that... These sasaengs, they don't think like normal people."

"Can someone please report them to the police."

"SM bodyguards used to be more aggressive?? Like please just don't let her get that close???"

"She is so scary."
