On March 15th, actress Yoo In Na guested on SBS's "Strong Heart" and revealed her envious feelings about the Park Han Byul and Se7en couple. The MCs had asked the actress if the couple were affectionate towards one another publicly. It prompted her to reveal, "On the last day of recording for 'My Black Mini Dress,' Se7en came to the film set. He was wearing impressive clothes and even came with chicken and a bunch of night time snacks for the staff members. When Se7en and Park Han Byul were sitting together, they weren't even talking, but you could literally see their hearts floating above them." Much to the amusement of the studio, MC Kang Ho Dong added, "I think Se7en is probably the busiest man in the world. He has to do events, has to visit his girlfriend's film sets..."
