A doting former exchange student gave an American high school senior a promposal she’ll never forget, traveling 4,500 across the globe to photobomb her prom photo with friends. Marybel Lindsey was left in a state of shock when she turned around to see Oeds de Boer holding a cardboard sign asking her to prom, completely unaware he would be traveling to the school from his native Netherlands. Oeds, from Friesland, Netherlands, met Marybel while he was an exchange student and she a freshman at McGavock High School in Nashville, Tennessee, and the pair have been in a long-distance relationship since. He dressed in an all-white tux and stood on a bridge behind Marybel and her friends while they posed for a prom photo. Then, having shown Marybel, 18, the photo with Oeds, 20, in the background, she turned around open-mouthed in disbelief before running into Oeds’ arms. The whole plan for the May 3 surprise had to be kept under wraps by Marybel’s family and friends, with the teenager’s mother, Melissa Lindsey, playing a key part in the organization.
