When I was very young, I read the story of a prince and a merchant's daughter.

I think it's called "bearskin man"

This man is not a prince, but a retired soldier. He met a devil. The devil gave him bearskin and money to put on and live. He put it on, took the money and lived in a businessman's house. The businessman has three daughters. The bearskin man asked the merchant to betroth a daughter to him and took out the money. Neither the eldest daughter nor the second daughter wanted to marry, but the younger daughter agreed to marry him for her father's sake. He split the ring in two, gave it to his little daughter for safekeeping, and then wandered around. A few years later, the soldier met the devil again. He forced the devil to wash and dress him. The soldier became a rich businessman (he said he used to be rich). He went to the merchant's house, and his eldest daughter and second daughter were very attentive to him. The little girl wept silently, and he put the wine in the original half ring. The youngest daughter found out his identity after drinking, and the eldest daughter and the second daughter jumped into the well and died. On the night when my little daughter married a soldier, the devil told the soldier that he had two souls.

I don't know if you're talking about this, but it sounds like this to me.
