On August 2011, a Chinese tourist came to Seoul for a holiday. Because she is a Super Junior's fan, she went to SM building in hopes that she would meet any Super Junior members. Then, in front of the SM building, she and her friends met two boys, that she believed are SM trainees. One of them were so tall, and the other was short, and really cute. They were bringing ice cream, and beverages cups. The shorter one said, "How does it tastes?" (the beverage), then the tall answered, "Delicious." Then, the shorter one took the taller guy's beverage cup, then he drank it. The taller guy laughed, then said "Hey! Why are you taking my drink?" Then he took the shorter guy's beverage then he drank it too. Both of them then laughed, then the taller guy linked his arms over the shorter guy. A few months later, the tourist found out if they were EXO-K's Baekhyun (the shorter guy), and Chanyeol (the tall guy).
