Ryeowook Active as the Fourth Runner in the Ministry of Health and Welfare's Blood Donation Campaign

I heard that blood supply is difficult during the summer and autumn.

It looked cool that you went all the way to the Seoul Red Cross Hospital Center in person to participate in blood donation.

It turns out that Super Junior has been active as blood donation ambassadors for the Korean Red Cross since 2007.

I found out that they have been maintaining their connection for nearly 20 years.
