I'm not sure as I don't know the details of this story. There must be a mother as the central character, and perhaps her children.
It's often about selfless dedication and sacrifice. Bulgarian stories show mothers going to great lengths for their children's well-being.
Since I'm not familiar with this particular Bulgarian story, but if we think about common elements in mother - love stories. The mother might sacrifice her own happiness for her child's future. For example, in a Bulgarian rural setting, she could give up her chance to remarry so that she can focus on bringing up her children. She might also be very protective, teaching her children about Bulgarian heritage and values. Maybe the story shows how she endures during tough times like wars or famines, always making sure her children are fed and safe.
Love and cultural identity are likely main themes. The story probably explores how love is shaped by Bulgarian culture, traditions, and the unique social environment of Bulgaria.
It's also possible that Kushina, Naruto's mother, could play a significant role even if she's not alive in the main Naruto storyline. The fanfic could explore her love for Naruto in a different way, perhaps through flashbacks or some sort of spiritual connection. And of course, characters like Iruka Sensei or Jiraiya could be involved as they have also shown parental - like affection towards Naruto in different ways.
The most obvious main character is the mother. She is the one whose story is being told. The stolen children are also key characters, even though they may not be present for much of the story in person. Then there might be antagonists, like the people who stole the children or those who try to prevent the mother from finding them. There could also be supporting characters such as neighbors or police officers who may play a role in the mother's journey.
Characters like Jack (from 'Jack and Jill'), Mary (from 'Mary Had a Little Lamb'), and Humpty Dumpty are main characters. They are simple yet memorable figures that children can easily identify with.
Obviously, the mother is one of the main characters. She is likely to be the central figure around whom the story revolves. Her actions, thoughts, and feelings are probably what drive the narrative forward.
I don't know for sure since I don't have the details of this 'Mother Game Story'. It could be the mother herself as the main character.
Perhaps there is also a neighbor or a friend in the story. This character could serve as a contrast to the mother, or they could be someone who provides support or conflict in the mother's life. For example, a neighbor might offer a different perspective on motherhood or family life.
The main character is the new mother. However, in the story, there may be some supporting characters that shape her experience. There could be a neighbor who has been through motherhood before and gives her some practical advice. There might also be a doctor or a nurse who helps her during the post - natal period, providing medical advice and support. And of course, her own parents, whose influence on her parenting style or her emotional state during this new motherhood journey can't be ignored.
