Does anyone know what this webtoon is?

I’m trying to find a webtoon I read a while back but I can’t remember the name at all! I’m pretty sure it’s a horror themed webtoon.

There’s a specific arc that is all that I remember where the protagonists recognizes an abnormality which is a sound eating tunnel. The tunnel eats sound and grows bigger. The only way they could escape it is by entering the tunnel in a car and tricking the toll gate into thinking some nails and clothes is a real person that needs to be sacrificed for the rest to escape the tunnel. They had to shout out that they were sacrificing the fake ‘person’ at the same time otherwise it wouldn’t work. I remember that the tunnel only eats sound that has the intention to communicate with another person and they almost didn’t make it out because there was a man in the group that messed up by telling a kid with his grandma to ‘shhh’ after he coughed.

Does anyone happen to know the name of the webtoon? 😭
