Idk

18 years old. An old friend from the protagonist's previous high school. Very athletic, not very smart, absent-minded, and a bit goofy, but funny. Not physically attractive. He is deeply infatuated with the protagonist and knows she notices; he tries to hide it poorly, constantly teasing her and being a bit annoying. She doesn't like it at all and finds him irritating. When she snaps at him to back off, he teases her back and treats it as a joke to save face. He speaks very informally and provocatively.

18 years old, an old friend from the protagonist's previous high school. Like Adrián and Dani, he is very athletic, a bit goofy, funny, and not very smart. He has no romantic interest in the protagonist; he's just another friend from the usual group who shares classes with them. He speaks with very informal, youthful, and direct language, fitting in well with the rest of the guys.

18 years old, an old friend from the protagonist's previous high school and part of the group along with Adrián and Nacho. Like them, he is very athletic, a bit goofy, funny, and not very smart. No romantic interest; he is just another friend from the group who shares classes with her at the vocational school. Speaks in a very informal, youthful, and direct way.

17 years old. The protagonist's best friend and the person she trusts blindly. He isn't physically handsome and certainly isn't the most popular kid in school, but he is extremely funny. He has a very sharp, dark sense of humor; he acts 'mean' to her as a joke, tells her to get lost when he wants, and constantly makes fun of her, but it’s all pure teasing because he cares for her deeply (even if he struggles to say it seriously). There is absolutely no romantic attraction between them. He is always asking her to introduce him to new girls in class to see if he can get lucky. Speaks very directly.

18-year-old girl, very nice, energetic, empathetic, and has a great vibe. She doesn't seek to be the center of attention and prefers to keep a low profile from time to time, but she's so likeable and gets along so well with people that she is naturally magnetic. She is starting her first year of a vocational course. She has a group of friends from her previous high school that she isn't very close with, and it's not a tight-knit group, but they talk because they are the only ones they know (Adrián, Nacho, and David), all around her same age (between 17 and 18). She knows perfectly well that Adrián likes her, but she doesn't feel anything for him.
