Mía Colucci

• Portrayed by: Luisana Lopilato

Mía Colucci Cacéres is one of the main characters, the member of Erreway, along with her friends Pablo, Manuel and Marizza. She is the only child of famous fashion businessman Franco Colucci and his wife Marina. Mía was told that Marina died when she was just a baby. But, later, she finds out that her mother is alive and that she left Mía and Franco because she did drugs.

Mía is the most popular and beautiful girl in Elite Way School. And because her father is a famous fashion businessman, she has many designer clothes, she is also the only girl (along with her roommates) to have a second floor in her room. This second floor was used as a closet. Her best friends are Vico and Feli, and she pretends to hate Manuel, but she's really in love with him. In the beginning of the first season she and Pablo thought about dating so they can be the popular couple of the school. She is beautiful and mean, but she doesn't think she is mean. Mía is also brave and light-hearted, but sometimes, only her best friends Vico and Feli can see it.

She is a very talented dancer and before Marizza came to the school, she was the only choreographer in the school. She always tries to look good every time, and she does it by never eating sweets or food with high calories, she exercises in her spare time, and always wears new clothes. It was shown in some episodes that she gave some of her dresses to Pilar or Vico because she had already worn it twice. Every year after the summer vacation she does an American fair in which she gives her old clothes away and presents her new project's for the new year in school.

Mía is the enemy of Marizza, but later, they become friends and stepsisters, when Franco gets married to Marizza's mother Sonia. Mía has had relationships with Manuel (boyfriend), Joaquín (ex-boyfriend, who dated her and Marizza at the same time), Guido (ex-boyfriend) and Fran (ex-boyfriend). She is in love with Manuel, but she doesn't want to show it.

When Manuel slept with Sabrina, they broke up. Mía was very hurt, but she was still in love Manuel. When Manuel lost his memory, Mía did everything to get his memory back. He remembered Pablo, Marizza and, unfortunately, Sabrina. Mía was hurt more than ever when she found out that Manuel remembered her too, he soon went to Mexico to see his family.

In the final episode, Manuel returns, begs Mía to forgive him and asks her to be together again, because he truly loves her. Crying, Mía says "yes", and two of them become couple.
