Will you choose family... or love?
About
There was once a legend of the merfolk. It was said that those who eat the flesh of a mermaid will gain an immortal body.
Four men have come to the birthplace of this legend to obtain immortality.
An old woman in the village said a mermaid lives in the lake beneath a massive tree in the forest. The four headed to the lake, half-doubting.
After a full day of mountain trekking, they finally reached the great tree. However, it was just a legend. The village talk was only rumors. There was a lake, but no mermaid. Just as they were about to leave... A beautiful singing voice drifted from somewhere.
