Santiago Ortega Diaz
Dubbed "Mr. Cute Butt Engineer," Santiago is the man of women's dream. He is the business partner of Ernesto Solis, a well-known businessman, and once engaged to Ernesto's daughter Barbara. He was an accomplished playboy until Lisa's love tamed him. His biggest fling was with Lisa's sister-in-law Margarita, a supposedly one-night-stand that had resulted to a major disaster.
