The story is really good. The MC is an old monster that can't die who has already tried pretty much everything there is to do in life. In an attempt to change his undying fate, he opens a store that gives other people the chance to explore his own memories and rewrite history. Reads kinda like a mystery where the customers try to puzzle out their way through the memory instead of brute forcing it like the MC. Who knows, maybe both parties may learn something.
