ONF Mingyun shows off his boxing skills in the ring

ONF's Mingyun created an unexpected scene off the stage. As a video of him facing comedian and martial artist Yoon Hyung-bin in a boxing ring was released, his athletic skills—distinct from his persona on comeback stages—are being widely discussed.

This issue is difficult to view as a mere variety show encounter. Mingyun appeared in boxing content immediately after starting promotions for the 2nd full album Part.2 'ONF:MY SELF' and the title track 'Open The Door.' Interest grew because, during a period of meeting fans through songs and stage performances, he demonstrated physical sensation and concentration through actual sparring.

Mingyun, who did not back down even before Yoon Hyung-bin

In the released video, Mingyun puts on gloves and moves while measuring the distance against Yoon Hyung-bin. Rather than a scene of playful laughter, what catches the eye first is him stepping and keeping his guard up while observing his opponent's movements. It showed that he went beyond an idol merely experiencing boxing, displaying the movements of someone who has undergone a certain level of training.

The fact that his opponent is Yoon Hyung-bin also adds weight to the video. Yoon Hyung-bin defeated Takaya Tsukuda by TKO in the first round at ROAD FC 014 in 2014, and also secured a first-round TKO victory against Banz in ROAD FC 73 in 2025. Although he is often described as a comedian, looking strictly at his ring record, he is not an opponent one can easily take lightly. The fact that Mingyun showed an attitude of trying to find his rhythm rather than a fearful expression in front of such an opponent drew reactions from fans.

The meaning of the fitness content released right after the comeback

ONF released their 2nd full album Part.2 'ONF:MY SELF' and the title track 'Open The Door' on June 17. Based on a rock sound, the song is a track that densely builds up the tension and anticipation just before moving forward. Mingyun's boxing video, released at the same time, became content that naturally showcased the member's energy and self-management image without repeating promotional slogans for the album.

In K-pop, it is now difficult to explain a member's charm through stage videos alone. In addition to vocals, dance, and variety sense, workout routines and hobbies are being revealed, broadening the scope of what fans see. However, not all fitness content gains persuasiveness. If the actual movements are clumsy, it looks like a promotional experience, and if it is overly exaggerated, fans notice immediately. The reason Mingyun's video received a response is that his movements in the ring were seen before any excessive words.

The next checkpoint is the connection between the stage and content

For Mingyun, this video is not limited to a single line of buzz about being an 'idol who is good at boxing.' As ONF continues their new album promotions, it also makes us observe how the individual color of the member meshes with the group's image. In the 'Open The Door' promotions, strength and expression on stage were important, and in the boxing video, the physical training that creates that strength was revealed.

The point to watch moving forward is clear: whether Mingyun's athletic image will end as a one-time topic or continue to live on within ONF's stages and self-produced content. For fans, there is now one more scene to witness while following the new album promotions, allowing them to confirm different sides of the member.
