some weird video i have been received (SEARCHING FOR ORIGINAL!!!)

Basically, my friend sent me this as a mp4 with no commentary.
When i asked him what is it about he replied "idk, my friend sent me this, i just know you're a fan of this type of shi".
I am searching for the original of this video.
The only i know, that it is a russian weirdcore/dreamcore/hyperpop soundtrack.
If anyone would even see my post, i hope you will help me find the og...
