She was a guest on the June 19th episode of MBC's 'Radio Star', where the MCs joked and told her, "You're from the same hometown as Eunji. We think you can do just as well as she has done."

She responded, "[I feel a little bitter about what you said]." When the MCs asked her what was the matter, Lizzy explained, "People say that because she did well after 'Reply 1997', I'm jealous of her and that I worship her." The MCs also mentioned Eunji's second drama 'Wind Blows in Winter', which also did well, and Lizzy responded, "Eunji acted in the standard dialect [Seoul dialect]. I can do it too, but while I was filming Rascal Sons', I was supposed to use [Busan dialect], so it's like I've once again been pushed back a bit."

Kyuhyun then asked, "Oh, you can act with the standard dialect?" and Lizzy cracked everyone up as she said, "Yeah, I've been doing it the whole time!" Everyone responded, "Oh, that's supposed to be your standard dialect?" She commented, "This is just due to how my personality is so when I'm speaking in standard dialect it doesn't sound like it, but I'm really using standard dialect." To prove herself, Lizzy tried to say the same sentence as the other guest on the show, but there was a bit of a difference.

Lizzy then raised her hand to say, "Wait." Turning to the camera, she spoke to the viewers as she said, "I'm not jealous of Eunji or anything like that, so please don't speak badly of me."
