SECRET's Hyosung revealed a creepy story about a past stalker during the latest filming of JTBC's 'We Are Detectives'.

After being asked if she's had any experience with stalkers, Hyosung shared, "There was an increasingly menacing fan who showed up at the agency because [he] couldn't wait a day [to see me]. For a few months, the fan came into the company and insisted on meeting me."

The well-known "bagel girl" also dished on what it was like being an underwear model for Yes, commenting, "Since I'm in a girl group, being overly sexy could receive a negative response, but [the photo shoot] came out lovely, so I was relieved." The male panelists remarked that they enjoyed her work.

This episode of 'We Are Detectives' airs on the 21st at 9:55PM KST.

The question is which one of you is it?
