On February 15th, TVXQ's Changmin guested on SBS's "Strong Heart" and shared some fun pre-debut stories which revealed a different side to the idols. Changmin confessed, "There are times when Super Junior's Si Won and Yunho's lifestyles overlap.� But if Choi Si Won is like a top tier corporation, Yunho is about in the middle. Choi Si Won's image is like that of someone who would wake up in the morning and luxuriously read English newspapers, but as for Yunho, he sits crouched on a chair and checks the economic news of the day on the computer." While reflecting back to when he first met him, Changmin continued, "At the time, Yunho was also unfriendly towards outsiders and was generally not close with everyone.� At one point, he even said, 'If you're going to come in and just leave, leave now.'" To the amusement of the studio, he added, "When we first started our dorm life, he called me to the living room and proudly turned on a video collection of him as Dana's back dancer and rapper.� Not only that, he showed the video to the other trainees as well!" -- Later on the show, Yunho also showed off his 'four leaf clover trick' with his tongue, which amused the studio greatly since other idols showed off talents like dancing or voice imitations. Changmin�hilariously added, "It's kind of weird staring at another person's tongue like this." Source: Newsen via Nate, Newsen #2 via Nate
