This is a story about blasphemy.
When holiness becomes prostitution, when piety becomes a shackle, the innocent boy's diary stops at the age of seventeen, when all love and protection are crushed into ashes——
Who is the real sinner?
The diary was torn into pieces, the Kingdom of God was burned, and the wooden boat passed through the fog.
The purple-haired ferryman remembers everything.
Therefore, she is the only redeemer and the only sinner.
