Sanmanhan Siseon, Busan Live Unreleased Footage… "No Malicious Comments if You Don't Get a Postcard," Cheerful Communication

Sanmanhan Siseon, a cast member of the music live content 'ONE HOUR', created a cheerful atmosphere by engaging in informal communication with the audience at the Busan performance site.

According to the unreleased video of 'ONE HOUR' released on October 7, 2026, it contains the conversation following the live broadcast held at KT&G Sangsangmadang Busan on June 26. In the video, after finishing the prepared songs, the cast continued conversations with the audience on various everyday topics.

"The water cost doesn't decrease"... From using water purifiers to confessing mineral addiction

The cast induced laughter from the audience by sharing technical difficulties felt during the performance and their personal daily lives. The cast mentioned that wearing in-ears makes it easy to match the pitch, but it is difficult to hear the sounds of the venue, and conversely, if they take off the in-ears, the pitch may be off, expressing a joking wish that "maybe one day a self-in-ear kind of function will develop in our ears."

In the everyday conversation, an episode regarding the use of water purifiers appeared. One cast member said they thought using a BRITA water purifier would decrease water costs, but they ended up continuously buying bottled water instead, expressing their habit of drinking a lot of water by describing themselves as "mineral addicted." This was followed by a confession that they love water so much that there are several water bottles in the waiting room.

"No malicious comments if you don't get a postcard"... A cheerful event for the Busan audience

Direct communication with the audience took place during the process of delivering postcards prepared at the performance site. The cast showed sides like a recreation instructor, contemplating how to deliver the postcards, suggesting to "go down" toward the audience seats, or pointing out specific audience members to ask questions.

In particular, during the process of distributing postcards, the cast showed affection for the Busan audience by saying, "Please don't leave malicious comments for us just in case you didn't receive one. If you don't get one, I'll bring something else next time." Additionally, they shared an anecdote about recently recording with Lee Jun, including an episode where they visited a restaurant after recording and ordered cola and beer because they could not drink alcohol.

A stage continuing with songs by Kim Min-ki and Yoo Jae-ha

Musical elements were also included in the middle of the conversation. After finishing the prepared songs, the cast shared stories about music, mentioning songs by Yoo Jae-ha and Kim Min-ki. The video concludes by capturing the atmosphere of the site after all the prepared songs were finished.
