The burgeoning popularity of regional dramas often brings with it a level of fan fervor that can oscillate between enthusiastic support and physical danger. This reality was starkly illustrated on June 1, 2026, when Singaporean actor Ayden Sng and Chinese actor Lyu Si Tong (also known as Lu Si Tong) were involved in a chaotic and dangerous mobbing incident at an airport. The actors, who have seen their international profiles skyrocket following the premiere of their latest project, were swarmed by a dense crowd that eventually resulted in both men being pushed to the ground. The incident has reignited a global conversation regarding the safety of public figures in the age of viral stardom and the responsibilities of talent agencies and airport authorities to ensure adequate security measures.
The Incident: A Breakdown of the Chaos
On the afternoon of June 1, video footage began to circulate across platforms such as X (formerly Twitter), Weibo, and Instagram, capturing what witnesses described as a "terrifying" scene. Ayden Sng and Lyu Si Tong were transiting through an airport—likely in mainland China or a major regional hub—following promotional activities for their new series. Despite the presence of a small security detail, the sheer volume of fans and "sasaengs" (obsessive fans who invade the privacy of public figures) overwhelmed the perimeter.
As the actors attempted to navigate the terminal, the crowd pressed in from all sides, ignoring requests from security to maintain distance. In the ensuing scramble, the physical pressure became unsustainable, leading to a collapse of the human corridor. Both Sng and Lyu were knocked off their feet. Eyewitness footage shows Ayden Sng immediately reacting to protect his co-star. Sng, who is taller and broader, was seen cushioning Lyu Si Tong’s fall and shielding him with his own body. In a display of protective instinct that has since gone viral, Sng cradled Lyu’s head to prevent it from hitting the floor and held him closely until they were able to be assisted back to their feet.
Even after regaining their footing, the chaos did not subside. Sng was observed maintaining a firm grip on Lyu, guiding him through the throngs of people who continued to thrust cameras and phones into their faces. Additional clips showed Sng patting Lyu’s hand in a comforting gesture, as the younger actor appeared visibly shaken and distressed. Reports from those on the scene suggested that Lyu was on the verge of tears due to the claustrophobic and aggressive nature of the encounter.
Background: The Meteoric Rise of Double Helix
The intensity of the airport mobbing is directly linked to the massive commercial success of Double Helix, a Boys’ Love (BL) romance series that premiered on May 28, 2026. The show, which blends elements of romantic drama with a unique narrative hook, became an instant hit across Asia and within international streaming communities.
Ayden Sng, a veteran of the Singaporean media industry and a prominent talent under Mediacorp’s The Celebrity Agency, has long been praised for his versatility and intellectual approach to acting. A graduate of Duke University and a former high-flying consultant, Sng’s transition into the regional Chinese-speaking market was highly anticipated. Lyu Si Tong, a rising star in the Chinese entertainment scene, provided the perfect foil for Sng’s performance. Their on-screen chemistry created a dedicated "CP" (couple) fanbase, a phenomenon in Asian entertainment where fans become deeply invested in the real-life interactions and perceived relationship between two leads.
In the days following the May 28 premiere, Double Helix trended in multiple countries, including Singapore, China, Thailand, and the Philippines. This rapid ascent to fame meant that the actors’ first public appearance following the launch was a high-risk event for crowd control.
Chronology of Events Leading to the Mobbing
To understand the failure of security protocols, it is necessary to look at the timeline of the actors’ recent movements:
- May 28, 2026: Double Helix premieres on major streaming platforms. Social media engagement metrics for both Ayden Sng and Lyu Si Tong increase by over 400% within 24 hours.
- May 29–31, 2026: The actors participate in a series of closed-door press junkets and fan-meeting recordings. During this time, flight information—often sold illegally by airport staff or third-party data brokers—begins to circulate among obsessive fan circles.
- June 1, 2026 (Morning): Large groups of fans begin congregating at the airport hours before the actors’ scheduled arrival. Security presence is noted as being standard for "VIP" transit but insufficient for a major cultural phenomenon.
- June 1, 2026 (Afternoon): Sng and Lyu arrive at the terminal. The initial orderly line of fans breaks as individuals rush forward to get closer looks or physical contact.
- The Incident: The crowd surge results in the actors being knocked down. Security is seen in footage struggling to regain control, at one point appearing completely engulfed by the mob.
Analysis of the "Sasaeng" Phenomenon and Fan Safety
The incident has drawn sharp criticism toward "sasaeng" culture. In the context of Asian entertainment, a sasaeng is a fan who engages in stalking or other behaviors that constitute an invasion of privacy. The behavior seen on June 1—pushing, shoving, and ignoring safety barriers—falls into the category of extreme fan behavior that prioritizes a "moment" with the celebrity over the celebrity’s physical well-being.
Netizens and industry observers have expressed outrage at the lack of boundaries. Comments on social media platforms highlighted the "animalistic" treatment of the actors. One widely shared post stated, "This isn’t support; it’s assault. They are human beings, not objects for your cameras."
The psychological impact of such events is significant. Actors subjected to airport mobbing often report heightened anxiety and trauma associated with public travel. For Lyu Si Tong, who is relatively newer to this level of intense international scrutiny, the visible distress noted by witnesses suggests a traumatic introduction to the darker side of fame. Ayden Sng’s role as a "protector" in this scenario, while praised by fans, also underscores the failure of the professional security apparatus intended to keep both men safe.
Security Failures and Legal Implications
The videos from the incident show a clear breach of safety protocols. In modern celebrity management, "high-risk" transits usually involve:
- Advance Coordination: Agencies coordinating with airport police to establish barricaded "green zones."
- VIP Exit Routes: Utilizing non-public exits to avoid main terminals when crowd sizes are predicted to be unmanageable.
- Tiered Security: A combination of personal bodyguards and local law enforcement.
In this instance, the security detail appeared to be composed of only a few individuals who were quickly outmatched by the hundreds of fans. This has led to calls for the actors’ respective agencies to investigate the lapse. There are also growing demands for airports to take a harder stance on "airport chasing." In recent years, airports in South Korea and China have implemented stricter fines and even blacklisted fans who disrupt terminal operations, yet the enforcement remains inconsistent.
Legal experts suggest that if injuries had been more severe, the fans responsible for the push could have faced charges of harassment or endangerment. Furthermore, the sale of private flight information remains a persistent legal "gray area" that continues to facilitate these dangerous gatherings.
Broader Impact on the BL Industry
The Double Helix incident is symptomatic of a larger trend within the BL (Boys’ Love) industry. The genre, which focuses on romantic relationships between male characters, often generates a uniquely intense level of fan devotion. This devotion is a double-edged sword; it drives massive commercial success and high streaming numbers, but it also creates a sense of "ownership" among fans who feel entitled to the actors’ physical space.
As BL dramas continue to move from niche markets into the mainstream—attracting actors from established industries like Singapore’s Mediacorp—the infrastructure for managing their popularity must evolve. The "CP" marketing strategy, which encourages fans to see the lead actors as a pair in real life, can inadvertently fuel the desire for fans to see them together in public spaces, leading to the kind of mobbing seen on June 1.
Conclusion and Future Outlook
The airport mobbing of Ayden Sng and Lyu Si Tong serves as a sobering reminder of the physical risks associated with modern stardom. While both actors managed to escape without major physical injuries, the footage of them on the ground remains a stain on the promotional cycle of Double Helix.
Moving forward, industry leaders are calling for a three-pronged approach to prevent a recurrence:
- Stricter Agency Accountability: Agencies must prioritize the physical safety of their talent over the "organic" publicity generated by airport appearances.
- Public Education: Fan clubs must take an active role in policing their own members and promoting "ethical fangirling" that respects personal space.
- Legislative Action: Stricter penalties for the sale of private travel data and more robust crowd-control mandates for public transportation hubs.
As Ayden Sng and Lyu Si Tong continue their promotional tour for Double Helix, it is expected that their security measures will be drastically increased. The incident has left an indelible mark on their fans and the industry at large, serving as a cautionary tale of what happens when the line between admiration and obsession is violently crossed. For now, the focus remains on the recovery of the two stars and the hope that their future travels will be defined by safety rather than survival.
