The Untold Mystery Behind a Great Wealth

This is a story of a poor, young man who exchanged his daughter's life for great wealth and a mansion in another world under the sea, and a beautiful girl who refuses to get married to him in his village, but rather accepts the hand of her nephew's best friend. She was thereafter made to live in the man mansion under the sea, still as his wife. But the day she makes it back to our world again, was the same day, the goddess who makes him wealthy takes away his life, because he fail to obey her instruction. Before she returned to her world, her husband and son have already found new loves and never wanted to take her back. So, taking her back was only made possible with the help of her mother-in-law's spirit, who had to visit the world again for that reason.
