In "The Return of Superman's" official preview of SEVENTEEN's guesting, Joshua and Jun were seen walking adorably with two babies UNTIL CARATs noticed this CREEPY detail.

What's Wrong With Photo: SEVENTEEN's 'Sasaeng' Caught In Official Preview

As a result, the fandom and a lot of internet users who saw it expressed disgust and fear about the sasaeng's behavior, leaving comments such as:

• "This photo gives me a chill down my spine. I feel so sorry for idols who were constantly under surveillance every day."
• "Imagine seeing photos taken without you knowing. It gonna feels like you are being watched 24/7."
• "Pledis and HYBE should sue them."
• "I can't imagine how idols must have been feeling every time they encounter sasaeng who always invade their privacy."

The fandom is especially making a consolidated list of "sasaeng" fansites on Twitter, while others are calling out the attention of Pledis and HYBE by tagging them in such posts.

Meanwhile, SEVENTEEN is not the only idol who was disturbed by obsessive fans earlier, BTS Jungkook also complained about sasaeng delivering food to his home address. As a response, K-pop fandoms are on red alert against sasaengs once again.
