Carla and Luis’s story began when they were undergraduates, attending the same summer program. Luis's roommate noticed Carla upon arrival and tipped him off to the pretty co-ed. Introductions were made, and two months later, they began dating. After a five-year long-distance relationship, they went their separate ways. But two years later, on August 8, 2008, they met up at the Empire State Building, in New York City. That rendezvous sparked a lasting romance, and on April 14, 2012, Carla and Luis tied the knot in another great city -- Vienna.
