I'm Really Fine

In the Korean comments

One top comment deadpans with a miniature sleep lesson: in translation, “The importance of sleep: Sleep is important for relieving physical and mental fatigue and maintaining health.” Another proposes renaming the video “The Side Effects of Two Hours of Sleep,” turning the title’s claim into the joke rather than accepting it at face value.

What the words mean

멀쩡해 (meoljjeonghae) literally describes someone as fine, intact, or having nothing wrong with them. With 진짜 (jinjja, “really”) adding insistence, the title reads here like a casual, exaggerated denial—a reading reinforced by the comment blaming what viewers see on two hours of sleep.
