Elena is surely a main character. Depending on the plot, there could be a teacher or a mentor figure who plays a significant role in her life. If the fanfiction has a romantic aspect, then the love interest would also be a main character. They would be involved in Elena's story, shaping her experiences and emotions.
In some 'One Day at a Time Elena Fanfiction', there could be a plot where Elena has to make a tough decision between two things she really wants. For example, choosing between going on a once - in - a - lifetime trip or staying to support a family member in need. Also, there might be a plot about her getting involved in a community project that changes her perspective on life. She could start out being reluctant but then find great joy and purpose in it.
Another plot could involve Elena dealing with a family crisis. For example, a family member gets sick and she has to take on more responsibilities while also taking care of herself, day by day. She could learn about the importance of family and self - care during this process.
Obviously, Elena herself would be the central character. Her friends could also play important roles. For instance, her best friend who is always there to support her through good and bad days.
I'm not sure exactly as I haven't read it in detail. But generally, it might be about Elena's daily experiences, her challenges, and how she overcomes them day by day.
I'm sorry, I haven't read this specific fanfiction. But you can try to find it on popular fanfiction websites like Archive of Our Own or Fanfiction.net.
One common theme is family relationships. Since 'One Day at a Time' focuses a lot on family, fanfictions often explore different aspects of the family dynamic, like how the characters support or clash with each other. Another theme could be the characters' personal growth and how they overcome challenges in their lives, just like in the original show.
One interesting plot could be the characters facing a financial crisis and how they come together to overcome it. For example, they might start a small business in the building to earn extra money.
