As actor Byeon Woo-seok's biological older sister's face was revealed and drew attention, it was confirmed that she left Korean Air Lines and is now living a completely private life.
On the 7th, OSEN reported that Byeon Woo-seok's sister previously worked as a flight attendant at Korean Air Lines, the country's largest airline, but she has since left the company and is living as an ordinary private citizen. However, on that day, suddenly on the internet, "photos of Byeon Woo-seok's sister from her days as a flight attendant" became a hot topic, and from the perspective of the sister living as a non-celebrity, it became an inevitably shocking situation.
Earlier, a photo of a woman said to be Byeon Woo-seok's biological older sister was posted on an online community and quickly spread.
The photo showed a woman working in a Korean Air Lines flight attendant uniform. She boasted facial features and a slender height no different from Byeon Woo-seok's, and her smiling appearance, in particular, drew attention for looking exactly like him. It turned out the person was Byeon Woo-seok's biological older sister, and a clip of her being interviewed by YTN during her time as a flight attendant was also released.
In the past, Byeon Woo-seok said his sister had worked as a model before getting a job as a flight attendant and that their age gap is five years. As a former model, she is also 173cm tall. For reference, Byeon Woo-seok's height is also known to be 190cm.
After rising to stardom with Lovely Runner, Byeon Woo-seok mentioned his biological older sister on tvN's 'You Quiz' in 2024, saying, "When my sister was preparing to work as a model, watching her made me think, 'Should I try modeling too?' And when she became a flight attendant, I even thought, 'Should I try being a pilot?' I was greatly influenced by my sister," confessing the close sibling bond.
But since Byeon Woo-seok's sister has left the airline and is living an ordinary life now, it seems necessary to refrain from excessive intrusion into her private life.
Meanwhile, Byeon Woo-seok is starring as the lead Ian Daegun in MBC's Friday-Saturday drama Perfect Crown. It has recorded a peak rating of 11.2% (Nielsen Korea nationwide), and its highest minute-by-minute rating reached 14.6%. According to the global OTT ranking aggregator FlixPatrol, Perfect Crown entered the Disney+ top 10 TV shows category immediately after its first broadcast, ranking fourth globally and first among non-English shows, and has steadily remained near the top. It has ranked number one in a total of 16 countries and regions, including Korea, Japan, Taiwan and Brazil, and appeared in the top 10 in a total of 47 countries and regions across North America, Europe and Asia, including the U.K., the U.S. and Canada.
