A first generation girl idol appeared on "Ohlala Couple."

On the upcoming Tuesday episode of "Ohlala Couple," actress and former SES member Eugene appeared as Shin Hyun Joon's first love. 

It's said that she made the cameo appearance because she has a good working relationship with the producer Lee Jung Sup, who also produced "King of Baking, Kim Tak Gu," after starring in the drama herself.

Word is that when she arrived on set, she first said hello to the producer and they went to work with a very light and happy heart after catching up for a short time.

The scene that she was in was in a flashback to Go Soo Nam (Shin Hyun Joon) when he was younger and she played his first love Min Young. Because it was a flashback, the two of them wore very retro and old-fashioned outfits and exaggerated hairstyles. 

Internet users said, "It's nice to see Eugene on a drama again!" "She can really pull off the retro look!" and "Shin Hyun Joon is so lucky!"
