On February 17th, Nichkhun's younger sister, Yanin, modelled for a cultural exchange fashion show between Korea's Hongik University and Thailand's Silpakorn University. Yanin was a runway representative of Silpakorn University, and she stunned the audience with her sophisticated looks. While the student-model was certainly applauded for her beauty, her celebrity ties also became a hot topic. Hongik University students and professors both recognized Yanin and greeted her, with some commenting, "Isn't that Nichkhun's sister?" The student fashion show wasn't the first runway experience for Yanin, as she had already participated in the '2009 Thailand Supermodel Contest'. This detail, in conjunction with her relationship to Korea's beloved Nichkhun, caused many netizens to become curious about the tall beauty. Inevitably, the photos induced the netizens to agree that "They're a family with superior genes." Source: Osen
