It probably http://www.mangago.zone/read-manga/canis/. But it’s a side story so you have to go down a few volumes
it's not this but thanks
the childhood friends one day got threatened by an anonymous call that someone has found the body and will return it if they worked for that person in disposing bodies
There is this manga, maybe shounen, about a group of childhood friends who are really close to each other and they murdered someone when they were small, they promised that each year they would come back to the place where they buried the body, I forgot the name, can someone tell me the name?
