Seems like the ALS' 'Ice Bucket Challenge' is finally reaching South Korea and the targets are none other than Korean celebrities.

It was started by Tim Hwang as he passed on the challenge to his good friends, Siwon, Brian, and Sean. This time, responding to Sean's nomination, actor Jo In-Sung takes on the challenge with the help of his co-star Lee Kwang Soo.

The video of Jo In-Sung is uploaded through his company's (IOK) Youtube channel. The actor started off with a message of his willingness and honor to do the challenge. He also nominated Lee Kwang Soo, Im Ju Hwan, and baseball player Cho In Sung.

Check out the video filmed after his drama shooting:
