Door to the Afterlife

During a trip to the plateau, we two strangers "accidentally" came into contact with an ancient ritual. "What they worship is not a god, but... A door that has stood for thousands of years and never fell down." The mysterious old man who appeared by the campfire revealed the secret, but also revealed an unknown mysterious world to us. This life and the past are entangled, love and hate overlap. Between reincarnation and death, a pair of cold eyes hide behind the truth, watching everything. "You know what? When this door opens, it will lead to the afterlife."
