Jade is very snobbish and is obsessed with her beauty and loves to go shopping. She is very dimwitted and is always in the position of ruining her and her brother's plans. Matias, on the other hand, is a very intelligent and calculative genius and is always the one coming up with plans to rob Herman. He always criticizes Jade for her incompence and has trouble controlling her. He is also very lazy and has a big appetite and Jade also criticizes him for this. They have a platonic love-hate relationship.
Jade and Matias were born to Jacinto LaFontaine and his wife. When they were kids, their mother died and their father ran out on them to start a life of crimes leaving them homeless. Sometime prior the series, Jade meets and falls in love with famous architect Herman Castillo, who is widowed and has a 17 year old daughter named Violetta.
In Season 1, Jade and Matias move in with Herman and start planning how to get Jade to marry him until Herman finally proposes. However, Jade grows jealous of Violetta's new tutor (and secretly her aunt), Angie Carrara, whom she fears will try to steal Herman away from her. Also, Violetta disapproves of her father's relationship with Jade knowing that Jade doesn't love him and plans on sending Violetta to boarding after they are married. When the two find out that Violetta is attending the Studio, they agree to keep her secret from Herman so that Violetta doesn't tell him about Matias's house arrest. At the end of the season, Herman finally realizes he doesn't love Jade and leaves her at the altar.
In Season 2, Jade and Matias now live in a small rented boarding house. Bent on getting revenge on Herman, they hire an actress named Esmerlda Di Pietro to make him Herman fall in love with her and leave him heartbrokem and penniless; however. Jade's jealousy keeps getting in the way of the plan.
- Although Ludmila Ferró is the main antagonist of the series, Jade & Matias are far worse being actual criminals as opposed Ludmila being a stereotypical diva.
