Siwon just went live on YouTube to support the comeback of Super Junior's vocal unit KRY!
He did an unboxing of the unit's first Korean mini album When We Were Us and even streamed and reacted to the their music video. No one can do a better job promoting SuJu than SuJu members themselves. Right, Siwon?
