What are y’all filming for?!

— Zi Yu

As the videos resurfaced, K-Pop fans—who are actually familiar with Zi Yu as the “handsome monk” from the interactive game Road To Empress—can’t help but express sheer shock at how the idol actor is being treated.

• “Wow, that’s intense.”
• “What the heck…?”
• “Ugh, they’re literal bugs.”
• “Wow. They’re shoving their cameras in his face when he’s visibly getting angry? That’s not even human.”
• “Wow, has sasaeng become a proper noun now? Unbelievable.”
• “There are people who sell these flight details… which is how Chinese sasaengs even follow K-Pop idols to Korea. But for local stars on local flights, it’s on another level.”
• “Oh, isn’t he the handsome monk from the Road To Empress? He has some serious sasaeng issues… The fact that no one even puts their phones down, it’s creepy.”
• “Crazy… Their stalking skills are on another level.”
• “Even when he’s screaming, they don’t lower their cameras…”

This actually makes way too many times that Zi Yu had to put up with frenzied stalker behavior from the sasaengs. Read more about the time he literally chased them away before reporting them to the local police:
