Lingerie-Clad Sasaeng Waiting For Underage Idol Outside Company Alarms Fans

Fans of CORTIS have demanded that the group’s agency take action against an alleged stalker.

According to fans, a fan of 17-year-old Seonghyeon has exhibited behaviors that would be concerning for any idol fan, especially given his age. In compiled evidence, videos posted by the alleged sasaeng themselves show her outside of the HYBE building.

The individual also seemingly shared that they would lurk around the HYBE building in order to pretend to have run into Seonghyeon. A post from another fan also alleges that she was seen at the HYBE building, but this time wearing “lingerie.”

• I’m freaking out; sasaeng Wang Si is now at HYBE downstairs wearing lingerie while playing “RedRed.”
• I’m gonna flip out, can any COERS chase away this auntie?! That person said she’ll wait for Seonghyeon after work, I wanna barf. She has tendencies towards exhibitionism and pedophilia.

Others have also mentioned seeing the individual wearing “inappropriate” outfits while following another underage idol, sharing photos of her in skin-revealing tops.

It is also alleged that the woman has made threats of sexual assault.

We still want to rape them (CORTIS) on the private jet heading towards the United States.

— OP

Fans of CORTIS have come together to report the alleged sasaeng to the company, while many have expressed shock over a grown woman behaving this way towards an underage idol.
