Mía falls in love with Miguel at first sight, but keeps quiet, since he starts dating her friend Celina.
However, Mía is unaware that Miguel came to Elite Way in an attempt to grow close to her in order to extract revenge on her father, Franco, who Miguel holds responsible for his father's death.
Despite her strong feelings for Miguel, Mía and Miguel argue constantly when they first meet.
Miguel is aware of Mía's relationship with Gastón and helps them protect their secret by telling Franco that he's dating Mía when Franco finds out about his daughter dating an older man who works at her school, even kissing her in front of her father, Gastón and the school's principal.
They start dating later on and declare their love for each other, with Miguel growing increasingly divided between going through with his plans and letting go of his past and moving on with Mía.
The most popular girl at Elite Way School, she comes from a wealthy and privileged family who lives in Mexico City.
Spoiled and self-centered, she however can be very loyal, attentive and tender towards those she loves.
Her best friends are Celina and Victoria "Vico", but she's also very close friends with Lupita.
