It's a visualization of Nelly's burnout of dealing with her mother-in-law and being a third wheel in the family. And Madelyn neglecting her daughter-in-law in favor of her grandson Allen.

But first a foreword.

Nelly comes from a small town, that was caught in middle of Kovellia-Moontain war. Once it over, Nelly runs away to capital city (Solastra) hoping for a better life. There she meets Daniel and she tries to woo him, in order to settle down in the city. And Daniel succefully falls for her. Since, he's unpopular with other ladies and he needs to continue his family line.

Nelly and Madelyn are strangers to each other, they didn't bother to get better acquainted. Nelly is afraid Madelyn will find out about her truth feelings, and Madelyn doesn't like that the spouse of her son isn't someone of their social circle (like another lawyer).

Once baby Allen is grown and he can play and learn, Madelyn occasionally starts visiting him and gives him stories about their heritage and what he must become once he's grown up.
