STAYC's Sieun Stuns with Unrealistic Proportions and 'Killer Legs' in 'Still Heart Club' Behind-the-Scenes Photos

STAYC member Sieun has captured fans' attention with her unrealistically perfect proportions and 'killer legs.'

On the 3rd, Sieun shared several behind-the-scenes photos from a photoshoot on her personal channel, captioning them with, 'Even if the time that sparkled generously fades little by little, it will live and breathe in your heart and mine #StillHeartClub.' The photos are from her appearance on Mnet's 'Still Heart Club,' which aired on the 2nd.

In the released pictures, Sieun is seen striking various poses in a white off-shoulder knit mini dress. Her long, perfectly straight legs were particularly highlighted in a full-body shot taken against a dark background. The flawless leg line and ideal proportions visible beneath her short hemline drew admiration from viewers.

Holding a microphone adorned with purple glitter and gazing at the camera, Sieun showcased her signature clear, bright eyes and elegant aura. Her radiant visuals, even in the dimly lit backstage setting, instantly captivated the audience.

The lyrics Sieun quoted are from the hit song 'Event Horizon' by singer Younha. In the previous broadcast of 'Still Heart Club,' Sieun delivered a moving collaboration stage of 'Event Horizon' with the Hanbin Kim team, receiving high praise from viewers.

Netizens reacted with awe, commenting things like, 'Is Sieun a real-life doll?', 'What's up with those legs... so beautiful!', and 'The 'Event Horizon' stage was truly touching! STAYC's Sieun is the best!'
