Last December, Big Bang and Jinusean's Sean made a surprise visit to a young girl named Jung Eun, who was fighting for her life against leukemia. Jung Eun was diagnosed with leukemia at the age of 15, and her one dream was to meet Big Bang's Daesung in real life, which led her father to leave a message on a Big Bang fansite. Sean immediately took notice of it, and he and the Big Bang members periodically visited the fan in the hospital. They even invited her to their concert in February, in the hopes that she'd be well enough to attend by then. But on January 28th, Sean revealed that Jung Eun had passed away. The artist wrote through his Twitter:

"Jung Eun has left for Heaven. Because of her father's love and the efforts of Big Bang's fans, Jung Eun was able to receive the precious gift of spending time with the members of Big Bang before she left. Jung Eun herself gave us a gift in return, in which she raised awareness for children fighting leukemia. I've earned a lot of things from Jung Eun.  Jung Eun was able to bring together the fans of Big Bang under one heart. Jung Eun became a great example of the power of social networking. Our country is the strongest IT nation in the world, and I'd like for us to think for once just what we choose to share through social networking.  I think it'd great if this section of our lives helped realize someone's dreams, gave hope, and shared love.  While fighting leukemia, this internet space was what helped Jung Eun realize her dream of meeting Big Bang."
