Su Man has had a strange disease since she was a child. As soon as summer comes, many weird fish scale patterns will easily grow on her legs.
She originally thought it was just a rare skin disease, but a series of accidents in that picturesque seaside town revealed her unique life experience.
As she gradually fell into a trap deeper than the Mariana Trench, she met a mixed-race mermaid, met a hypocritical angel, and saw Satan who was working hard to dig a grave for God.
