Very confusing short film (S)

I remember watching this short film a year ago or that was korean and i remember that it was stopmotion. I believe it had very few views. I think it also may had something to do with teeth? I don't believe it was horror though. The area that it took place in was very empty.  There was an alleyway where the main character did an exchange with something. There was also a cat involved somehow. Sorry that I don't remember it too well, but I hope what I can will can help.
