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?
