In this world, when people die, their souls enter a place called the Netherworld.
There, the dead continue to face the unresolved emotions and regrets they left behind in life. By reliving their past, they search for a path to redemption.
Everyone has a guide. These guides are people or things that once affected their lives, and they appear in many forms.
Some souls cannot let go and sink into the dark abyss, becoming resentful spirits that wander without rest.
To escape the prison of death, souls must overcome their inner struggles, face challenges from their opponents, and gradually accept their own past. Only then can they find a new path to rebirth in the light.
On this journey, seemingly quiet yet full of strife, they must not only face their past, but may also become entangled in the complex relationships and conflicts between other, unfamiliar souls.
Theme: Don't cling too tightly to the past; cherish the present.
