G-Dragon along with G-Market is sponsoring an event called “1.25 Miracle Marketplace” to raise money to help those less fortunate. Below you can view the commercial for the event or click the link to view the actual G-Market page. It seems that in exchange for the donation you will receive a photo or MP3 of one of the contributing celebrities. We are not sure any of the specifics otherwise.
