A uniform ad from almost six year ago has been gaining much attention due to its feature of TVXQ's Yunho and SNSD's Seohyun. The poster was released back in 2005, and it was put up in the entrance halls of some schools. At the time, Yunho had�already debuted as part of TVXQ, but Seohyun was just a middle school trainee. Fans of both idols gushed over their baby faces, and laughed at Yunho's spiky haircut. Meanwhile, netizens commented, "Seohyun was pretty even before she debuted", "Totally fresh uniform couple", and "Mr. Handsome and Miss Beautiful - constant like a storm." Source: MyDaily
