Place it at the start of a sleepless-night edit, then follow it with the snore sound once the joke has landed, so the late-night setup comes first and the punchline about finally falling asleep closes the clip.
关于此声音
Katernai Nemuranai is a short Japanese spoken phrase built around the words for not being able to sleep, delivered as a direct, late-night statement. It feels restless and a little weary, like a message sent when the house is quiet and sleep still will not come. That tired, wide-awake mood makes it easy to recognise, and easy to answer with a joke or a sympathetic reply.
