Who should ferry the souls stranded in the world due to their obsessions, and the ferryman's own obsessions?
Core setting: The protagonist is a ferryman in the spirit world, responsible for guiding souls stranded in the world due to obsession to reincarnation. He has seen countless obsessions: lovers waiting for love, mothers seeking revenge for their children, scientists regretting their careers. He never got involved in the obsession of souls until he met a soul that looked exactly like himself - that was his dead brother. The elder brother's obsession is "I hope my younger brother can let go of his guilt". The protagonist then discovers that he became a ferryman precisely because he felt guilty about his brother's death. In the end, he reconciled with his brother and found his way back.
Intention: The power of love and affection!
