Thank you for putting on your coat when you passed me. What are the allusions?

This is a story about a woman who died, a man passing by, putting his clothes on the woman, and the woman came to repay her kindness in the afterlife and stayed with the man for a while. But in the end, the woman was not with him, because another man buried her in a previous life, and she was coming to spend the rest of her life with her.
