Actor Lee Kwang-soo has transformed the fan communication platform Bubble into a daily spectacle following his launch, flooding subscribers with dozens of rapid-fire messages and drawing celebrity fans including Kim Woo-bin and Doh Kyung-soo into paid subscriptions.
What began as a simple introductory greeting quickly escalated into an unyielding stream of digital chatter. Actor Lee Kwang-soo launched his official presence on the Bubble fan communication platform on August 1, though extensive messaging surges made headlines. After grappling with unfamiliar platform settings on his first day, the actor quickly mastered the interface, sending more than twenty messages by the morning of his second day and prompting fans to joke about the sheer volume of his notifications.
Actor Lee Kwang-soo Floods Fan App With Daily Messages
Fans quickly discovered that subscribing to the actor’s chat room offered an experience closely resembling a live variety show rather than a standard celebrity broadcast. Subscribers woke up to dozens of unread alerts, with one fan noting that 27 messages had accumulated overnight while another reported a backlog of 56 notifications.
More messages had piled up as soon as fans opened their eyes, and some individuals remarked that the stream felt less like a fan communication app and more like watching a live variety show. He confessed that he was constantly checking the app, stating, Ah, I can’t take it anymore,
What should I do?
and I keep opening and closing the bubble app.
When fans asked whether he was addicted, he responded, Part of me also wants to look a little busy,
and Tie me down,
which drew laughter.
The actor made little attempt to hide his immersion in the app. He openly confessed to constantly checking his phone, telling subscribers I think I’m addicted to this. What should I do?
When users jokingly urged him to quiet down or called him noisy, he fired back with characteristic humor. I got roasted as soon as I started, and it woke me right up,
he noted, as reported in coverage of his early chat sessions.
Beyond casual banter, the actor used the platform to offer advice to subscribers preparing for job interviews and high school students. He also engaged in lighthearted negotiations when fans suggested he wrap up his late-night messaging marathons, telling them to hold on a little longer.
Kim Woo-bin and Doh Kyung-soo React to the Messaging Surge
The actor’s digital enthusiasm did not go unnoticed by his peers in the entertainment industry. A wide circle of fellow performers rushed to secure paid subscriptions, including IVE members Rei and Liz, RESCENE members Liv and Won, IZNA member Jung Se-bi, tripleS member Yoon Seo-yeon, KISS OF LIFE member Haneul, and Lucy member Choi Sang-yeop, as detailed by reporting on his celebrity subscriber base.
Close friends and fellow actors also weighed in on the sudden trend. Actor Kim Woo-bin expressed immediate curiosity about the platform.
Kwang-soo hyung started Bubble? Where can I see it? I want to talk to him. I heard Kwang-soo hyung is famous for being funny. If he’s funny even on Bubble, what are we supposed to do?
Kim Woo-bin, Actor
Doh Kyung-soo voiced similar surprise during a public performance, admitting he had no initial idea his colleague had joined the service. The platform obsession even crossed over into live concert settings. While watching a stage performance alongside Kim Woo-bin, Lee was spotted glancing intently at his phone. When fans asked if he was messaging during the show, the actor explained that he had acted quickly to avoid detection, adding that staff members had previously caught him mid-chat and walked away. When fans asked him during a performance whether using the service during a concert was truly addictive, he explained, I acted really swiftly to avoid getting caught,
and added, I suddenly remember spacing rules,
Earlier, Kyung-soo’s staff members said, ‘Are you on Bubble again?’ and left,
and Is there any way to use Bubble without getting caught by anyone?
which elicited laughter.
