SK Sunny, Korea's largest volunteer group of college students, was established with the goal of nurturing young talents who can bring change to our society. Since its foundation in 2003, members of Sunny have been sharing happiness with people from all quarters of society through creative ideas and voluntary, initiating, and practical activities. Sunny focuses on various social issues such as alienation, safety, environment, education, and youth, and carries out creative and sustainable social change programs to tackle such problems. Around 3,500 college students from ten regions in Korea and six provinces in China join and develop with Sunny every year to become members of Youth Social Innovator.
