South Korean actor Song Joong Ki has become the center of online discussion after an older airport video resurfaced and went viral on social media, prompting widespread reactions about his appearance and the natural effects of aging.

The clip, originally filmed at Incheon International Airport in 2025, recently gained renewed attention after being shared on Instagram Threads. As the video circulated across various online communities, many users began commenting on what they perceived as noticeable changes in the actor’s appearance compared to his younger years.

Song Joong Ki, who rose to international fame through hit dramas such as Descendants of the Sun and Vincenzo, has long been regarded as one of Korea’s most recognizable leading men. Because of his image as a youthful and charismatic star, even small changes to his appearance tend to attract significant public attention.

The resurfaced video quickly generated thousands of comments. Some netizens expressed surprise at how much the actor had changed over the years, noting that he now appears more mature than during the peak of his early career.

Others argued that the discussion itself was unfair, pointing out that Song Joong Ki is approaching his mid-40s and remains considerably more youthful than many people his age. Supporters emphasized that aging is a natural process and that public figures should not be expected to maintain the exact same appearance they had a decade earlier.

However, the online conversation took a more controversial turn when some commenters began linking his appearance to his highly publicized divorce from actress Song Hye Kyo.

The former celebrity couple, once nicknamed the “Song-Song Couple” by fans, married in 2017 after starring together in Descendants of the Sun. Their relationship attracted enormous attention throughout Asia, making their separation in 2019 one of the most discussed celebrity breakups in Korean entertainment history.

Although there is no evidence connecting Song Joong Ki’s appearance to his past divorce, some netizens speculated that he appeared noticeably different after the end of the marriage. Others rejected that claim entirely, arguing that six years have passed since the divorce and that any physical changes are far more likely to be the result of normal aging, lifestyle changes, career pressures, and personal responsibilities.

Several comments also referenced Song Joong Ki’s current family life. Since marrying former actress Katy Louise Saunders and becoming a father, some users suggested that the demands of parenting may have contributed to a more mature appearance. Others joked that raising children can make anyone look older, regardless of celebrity status.

The discussion also revealed a broader debate about public expectations surrounding aging celebrities. While some people mourned the loss of the youthful image that first made Song Joong Ki famous, many others argued that viewers often hold actors to unrealistic standards.

Supporters noted that the actor continues to maintain a successful career and remains widely recognized for both his acting ability and screen presence. They also pointed out that comparing a 40-year-old actor to footage from his early 30s creates an unrealistic benchmark that few people could meet.

Ultimately, the viral discussion appears to say as much about public attitudes toward aging as it does about Song Joong Ki himself. While opinions remain divided, many fans believe the actor still looks healthy and distinguished, viewing his current appearance as a natural reflection of time rather than a dramatic transformation caused by any single event in his personal life.

As the debate continues online, one thing remains clear: years after his divorce from Song Hye Kyo, Song Joong Ki continues to attract intense public interest, whether for his acting projects, family life, or even the way he ages in the public eye.
