Yoochun's noona fans have been revealed to have donated to charities under his name.
On January 22nd, his label C-JeS Entertainment commented, "Yoochun's fansite 'Blessing Yoochun' performed meaningful community service for the new year." The fanclub is made up of fans who are over the age of 30. In 2010, they donated 10 million KRW (approximately $9,500 USD) for burn-related surgery for child Park Hyun Bin.
Since then, they have donated 80 million KRW (approximately $76,000 USD) to various charities. They donated to help children with cancer, build study rooms for children in need who suffered from water damage, and to provide free food at children centers.
The fanclub has been continuously donating to anyone they already met once through donations. When they heard that Park Hyun Bin needed more money for his second surgery, they donated an additional 7 million KRW (approximately $6,600 USD).
