A boy with an ordinary appearance and an ordinary life experience accidentally meets the mysterious girl Kyoka.
This is where the weird stories begin.
Everything revolves around that elusive man. Jinghua calls him "Master", others call him "A Deng", and he calls him "Deng Gui".
In other words, no one knows who he is, and he himself has forgotten it.
The ordinary boy who was dragged onto the pirate ship by Adeng witnessed the grudges and grudges from a hundred years ago. They fell in love across thousands of mountains and rivers, fell in love across the cold prison door, and fell in love across the cycle of life and death.
Black Prison is the natural law that governs the cycle of life and death. The criminals imprisoned in the black jail are also poor people who have been teased by fate.
They just want to be together.
Seventeen prison guards guard the gate of the black prison, preventing lovers from getting married. But none of them wanted to break this sad law.
Of course, Adeng, one of them, also thinks so.
