If you haven't heard of the ALS Ice Bucket Challenge because of K-drama watching, you may want to know that the wildly successful charity challenge has arrived in South Korea, and Jo In Sung, star of It's Okay, That's Love, just got drenched. Watch the video here.

While filming for It's Okay, That's Love, Jo In Sung found out he was challenged by singer Sean, and he made the time to do it. Before starting, he said that he was very happy to participate in this meaningful activity. He hopes that the challenge will not only help ALS patients, but will also give hope and courage to anyone who has been injured mentally or physically.

His co-star in It's Okay, That's Love, Lee Kwang Soo apparently did the honors.

According to the rules of the challenge, Jo In Sung then named these three to the challenge next: Lee Kwang Soo, actor Lim Hu Hwan, and baseball player Jo In Sung.

According to the ALS Association's website, "Amyotrophic Lateral Sclerosis (ALS), often referred to as "Lou Gehrig's Disease," is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their death. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. With voluntary muscle action progressively affected, patients in the later stages of the disease may become totally paralyzed."

The ALS Association said on August 19 that the Ice Bucket Challenge has raised over $22.9 million in donations.
