Actor Yoo Ah In's benevolent act of charity towards a child leukemia patient became belatedly known to the public. 

According to what Korea Childhood Leukemia Foundation said on October 13, Yoo Ah In donated the funds necessary for a 7-year-old leukemia patient to undergo a bone marrow transplant in September at a hospital in Seoul. At the time, the child was in the midst of battling cancer and is currently recovering from the surgery. A rep from the Foundation stated, "To protect the patient's personal information, we can't give any specific details, but Yoo Ah In did sponsor the costs of surgery."
