J.Y. Park also shared about the time Rain opened up about his ill mother. He explained, "One day, Ji Hoon said he has something to tell me. He then revealed his mother is very sick and asked me for help. I went to his house right away and saw that his mother was very ill. But he never told me that."�

He continued, "She passed away early, and because of my memories with him, I cried along with Rain when he won Daesang. I think I cried because I knew his feelings (and situation)." J.Y. Park also picked the moment Rain won Daesang as the most memorable in his life and said,�"I think that was the only time I've ever cried along during an acceptance speech."
