STAYC's Sieun Captivates with Emotional Collaboration on 'Still Heart Club', Delivers Moving 'Beyond the Horizon' Performance

STAYC member Sieun has enchanted viewers with a deeply emotional performance on Mnet's 'Still Heart Club'.

Broadcast on the 2nd, Sieun joined forces with Team Hanbin Kim for a special collaboration stage. Upon Sieun's arrival for the 'Collaborative Unit Battle' in round 4, the Team Hanbin Kim members expressed disbelief, feeling as though they were dreaming. Sagisomul, in particular, was overwhelmed, recalling how he used to watch STAYC on TV during his mandatory military service.

Sieun's participation injected fresh energy into Team Hanbin Kim. When asked for her secret to capturing fans' hearts, Sieun shared playful gestures like winks and air kisses, and even taught them the 'press-press dance' from STAYC's hit song 'ASAP'. She then proposed Younha's 'Beyond the Horizon,' a song filled with lyrical depth and emotional points, suggesting it would showcase a different charm compared to their previous stages.

Sieun harmonized with Sagisomul on vocals, diligently working to perfect their harmonies through practice. She offered words of encouragement to Sagisomul when he became discouraged after mistakes, saying, "Don't lose your spirit." She also soothed the nervous members before the main performance, leading the atmosphere with her calm demeanor. The stage, guided by Sieun's leadership, delivered a profound impact with its perfect harmony and touching performance. Sieun further captivated the audience with her relaxed stage presence, including an air guitar performance.

Meanwhile, STAYC recently concluded their world tour 'STAY TUNED,' meeting fans in Asia, Oceania, and North America. They are also set to release their first full Japanese album, 'STAY ALIVE,' on February 11th.

Netizens praised Sieun's stage presence, commenting, "Sieun's ability to control the stage is truly amazing," and "Hearing Younha's song in Sieun's version is refreshing and good." Many felt that Team Hanbin Kim members were able to perform better after relaxing thanks to Sieun.
