Yooo. I've been trying to find this song I like that is used on TikTok by Japanese people. It's a song where a girl is counting up from 1 (in Japanese), and there's this mellow piano sound in the back with a slow, steady metronome going 45 BPM and it sounds every time the piano stops (or right before the girl says the next number). The piano part kind of reminds me of what the left hand plays in the song River Flows In You.

If anyone knows the title to what song I'm talking about please comment below! Thank you!

It's the song at 8:42

I tried Shazam already but no results came up. I also searched up the user's name on TikTok and found their video to see which sound they were playing but it said it was an original sound. I swear I swear I have most definitely heard it in a few other videos.
