Teresa befriends her teacher Arturo de la Barrera (Sebastián Rulli), a prestigious lawyer who accepts to pay for her college studies.

However, seeing that her best friend Aurora (Ana Brenda Contreras) fell in love with Mariano, Teresa, filled with jealousy, gets back with him.

But, seeing that it will take time for Mariano to have a career and money, she finally decides to pick Arturo, whom she lies telling him that she is very unhappy with her parents.
