#CCC is just a song in HHH and does not happen in-universe

[virnuileva-peto]

Didn't have time yet to analyse Huhhahhei but so far I have this one theory. Mostly a wild guess and I can't wait to see other explanations, especially from Finnish speakers who could point out all the linguistic details. (I don't even speak Finnish, have patience)

The story, as explained in the insta live, is that a lady is boldly flirting with Käärijä, and he is a bit shy about it but generally likes it. They spend the night together, and Käärijä enjoys it a lot, but in the end he is worried if she will still be there in the morning.

The part "huh (huh) hah hah hah huhhahhei" has the same rhythm as "Cha cha cha cha cha cha chaaa" (especially if you ignore the second "huh"), suggesting a connection between HHH and CCC.

My interpretation is that the lady is a metaphor for fame, which came abruptly, surprised Käärijä and swept him off his feet, and he decided to just roll with it, and while he greatly enjoys it, ultimately he's worried it will all be gone without a trace really soon. And since the fame came from CCC, you can hear an echo of that song here as well.
