After mysteriously disappearing out of sight from his fellow BEAST members on numerous stages including the 2009 MAMA, Doojoon stirred up netizens and fans in a debate over the reason why. Some had assumed he had withdrawn from activities due to an injury, while some believed he had officially quit the group. Don't worry, none of those rumors are true - Doojoon was actually volunteering in Africa, digging wells for the villagers. What an angel! I swear, the Cube Entertainment artists, 4minute and BEAST are just absolutely amazing! Anyway, it turns out Doojoon was actually cast in MBC's Sunday Sunday Night's new show, Danbi (Acronym for Only One Secret in Korean). The show will focus on helping out people in need around the country and occasionally overseas. A representative stated:

"Yoon Doojoon traveled to Zambia, Africa with actress Han Ji Min and helped to dig wells [to provide fresh water]. The top-secret filming did not allow the managers as well as the family members to attend. Everything will be revealed on our showcase opening on the 25th."
