Recently, Tohoshinki was announced to be working with the 7 & I Group for their summer campaign. On the promotional CM of Sogo-Seibuâ€™s â€œSilver Bearâ€™s Silver Cardâ€, the boys had dances together with the mascot, Silver bear, alongside with their new song â€œI Donâ€™t Knowâ€. Â Because the silver bear was only digitally added using a CG, Yunho sadly expressed, â€œI wanted to meet the bear but it was added using CGâ€¦â€ then he suddenly looked on the bear who was placed at a side and asked, â€œHave you been well?â€ and this creates much laughter. And also regarding the dance choreography for their new song, Changmin stated, â€œHonestly speaking, we only did 15 seconds of the dance for the CM,â€ and he added, â€œIâ€™m looking forward to seeing what the whole thing will look like, so letâ€™s anticipate it together.â€
The shooting was done with both Japanese and Korean staff that is why Yunho had expressed, â€œItâ€™s been a long time since weâ€™ve worked with the Japanese staff so I was nervous, but we managed to settle in quickly, and did the shoot with a good feeling.â€ Changmin had then stated, â€œI was interpreting (for the staff).â€ The two had then showed their closeness to each other after they had watched the complete CM. Yunho praised the bear stating, â€œHe danced better than we did.â€ Changmin then expressed, â€œItâ€™s a pity that his arms and legs are too short,â€ in where Yunho had replied, â€œBut that canâ€™t be helpedâ€ and both of them had laughed with their own words.
Also it was announced that they are going to participate in â€œa-nation 2011â€ as Yunho commented, â€œIâ€™m happy to be able to participate (in a-nation) again after two years. I want to work hard, and will not be defeated by the heat,â€ and Changmin stated, â€œa-nation is a big summer event, andÂ we are able to participate in it again after two years, so I want to show a passionate stage.â€ In regards with the Tohoku Earthquake, Changmin revealed, â€œ(The victims) must have suffered a lot. I want to tell them, let us work hard together to overcome this (disaster)â€
