Prologue:

Faith, Hope, and Love

Three simple words that all of us probably have heard about already. But the question is, how deep do we know it? When exactly do we start to have faith? How much does it take for us to keep a hope up? And love, for how long do we have to keep on loving? Does it have any boundaries? Perhaps yes, perhaps not.

Shin Ryujin, a miserable young man that holds a grudge towards his own life met a wandering lone spirit Hwang Yeji, which happens to have difficulties of attaining the afterlife. Will he help her out or is her that's going to help him out of his miserable state? Who's helping who? Can they change their fate?
