In the Korean comments

The camera movement becomes a cat-camera joke. One comment reads, in translation, “Isn’t Han Taesan basically a cat, following the camera like that?” Another asks whether the clip is filmed from a “cat pet-cam” viewpoint, while a third says they were so busy looking at his face that they did not realize it was a camera advertisement.

What the words mean

“탯냥이” (Taetnyangi, “Taesan-kitty”) blends a shortened form of Taesan’s name with the Korean sound associated with cats and an affectionate word for “kitty.” Here it is a playful fan nickname that supports the pet-camera joke, not a literal reference to a cat.
