I don't know for sure. But I assume the sister is one of the main characters. There might also be other family members like her parents, brothers, or other sisters who could be important in the story since it's about a sister's secret.
Without having read the story, it's difficult to determine the main characters precisely. However, the sister is the central figure. There could be a love interest in the story, someone she's involved with and the secret might be related to their relationship. There may also be an antagonist, perhaps someone who is trying to expose her secret for their own gain or someone who is against her because of the secret. And of course, her family members, who will likely be deeply involved in the consequences of the secret, whether they know about it or not.
Well, the sister herself is obviously a main character. And perhaps her best friend who might be the only one she has confided in about her secret.
Obviously, the main characters are the brother and the sister. But there could also be other minor characters like their pet dog that might be involved in their secret somehow.
Since I haven't read it, I can't say for sure. But likely the sisters would be main characters, perhaps their parents or other family members could also be important characters in the story.
Typically, the main characters would be the two sisters involved in the secret relationship. There might also be their parents or guardians who are somehow related to the secret.
It could be a variety of characters. It might be a single mother who has a secret dream of going back to school and she dares to take the steps to make it real. Or it could be a group of friends who share a secret dream like starting a community project and they all dare to dream it into existence.
One main theme could be self - discovery. She might be on a journey to find out who she really is, away from the expectations of her family and society, and this process is full of secrets.
I'm not sure specifically as I haven't read it. But it could be about a secret that a sister has been keeping, perhaps something related to family, her own personal life, or a past event.
I'm not sure specifically as the title is rather ambiguous. It could be about a secret that a sister has been keeping, perhaps a family secret, a personal secret like a hidden talent or a past event that she hasn't shared with others.
The real story could involve family drama, personal struggles, or even a long-kept promise. Maybe the sister is protecting someone or has a hidden talent she's afraid to reveal. The possibilities are endless.
As there is no information given about this story, it's impossible to say who the main characters are. They could be ordinary people with an extraordinary secret, or they could be fictional characters created for a specific plot.
