Ock Joo Hyun recently returned under the spotlight with a surprise broadcast appearance after being away for some time. 

Unfortunately, her almost unrecognizable transformation left many viewers confused during the latest episode of SBS's 'Kkokkomu,' where she made her guest appearance.

Decked in a simple light pink button-down shirt and sporting a new light brown hair color, Ock Joo Hyun seemed far from her old self, leading to a considerable buzz among viewers. Netizens struggled to recognize her until they heard her distinctive voice.

The 'Kkokkomu' episode that featured her as a guest delved into the infamous 1987 KAL 858 plane bombing incident. Throughout the episode, Ock Joo Hyun's reactions and shock became evident as she listened to the chilling recounting of the historical event.

Yet, rather than focusing solely on the intriguing story, viewers found themselves engrossed in analyzing her face and talking about her altered features. Many have taken to various social media platforms to discuss the physical transformation of the former Fin.K.L member.

Some comments were: "I only recognized Ock Joo Hyun because of her voice," "Can't pin point what's different but she looks like another person. She was pretty before; why did she do something?" "She touched her nose it seems...she was prettier before," "Her face is different," "I started watching from the middle of the show, so I didn't know who she was," "She looks like a different person," and more.
